total stopping distance is the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop. It consists of two main components: the thinking distance and the braking distance.

total stopping distance refers to the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop. It is composed of two main components: the thinking distance and the braking distance.

The thinking distance is the distance the vehicle travels during the driver's reaction time. It is the time it takes for the driver to perceive a hazard and apply the brakes. Factors that can affect the thinking distance include the driver's alertness, distractions, and the speed of the vehicle.

The braking distance is the distance the vehicle travels while the brakes are applied and the vehicle decelerates. It depends on factors such as the speed of the vehicle, the condition of the road, and the efficiency of the brakes.

Therefore, the total stopping distance is influenced by both the thinking distance and the braking distance. It is important for drivers to maintain a safe following distance and be aware of their vehicle's stopping capabilities to ensure they can stop in time to avoid collisions.

Total stopping distance includes b. The distance the car travels during the driver's reaction time

The distance a car travels during the driver's reaction time and the distance it travels while the driver is braking are included in the total stopping distance. It's possible that a driver's foot isn't on the brake when they realise they need to stop the car. The car, for instance, is going at a constant speed.

The moment the driver realises that the vehicle needs to be stopped, his or her foot is moved to the brake pedal. The reaction distance is what we refer to as. The car slows down as soon as the brakes are deployed. The braking distance is the length of time needed to stop. Total stopping distance is calculated by summing reaction distance and braking distance.

Answer:B

Explanation:

.03 of an hr is 2 mins and if it takes 2 mins to drive 4 miles enter it in pace calulator you are going 120mph so the closest to 120 is 133mph

The kid is breaking the speed limit of 45 miles/hr since he is going at 133.3 miles/hr.

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Since the distance to the mall is 4 miles, the time taken is 0.03 hours, hence the speed is:

Speed = distance / time

Speed = 4 miles / 0.03 hours

Speed = 133.3 miles/hr

Hence the kid is breaking the speed limit of 45 miles/hr since he is going at 133.3 miles/hr.

3.125×10²¹ N/C

Explanation:

Electric Field: This can be defined as the force experienced per unit charge. The S.I unit of electric Field is N/C

Applying,

E = F/q.................. Equation 1

Where E = Electric Field, F = Force experienced, q = Charge of an electron.

From the question,

Given: F = 500 N, q = 1.6×10⁻¹⁹ C

Substitute these values into equation 1

E = 500/(1.6×10⁻¹⁹)

E = 312.5×10¹⁹

E = 3.125×10²¹ N/C

The ranking is like, D (next to the end of the wrench, B=E (middle of the wrench), F next to the top of the wrench, A (top of the wrench), C (bottom of the wrench)

Given,

Forces;

D > B=E > F > A > C

We have to rank these forces (a through f) on the basis of the magnitude of the torque they apply to the wrench, measured about an axis centered on the bolt

Magnitude of torque;

The ratio of the force's and the lever arm's magnitudes yields the torque's magnitude. Force has a dimensional formula of [M1L1T2], whereas a lever arm has [L]. Consequently, [M1L2T]2 is the dimensional formula for torque.

Therefore, the ranking of the torque is D (next to the end of the wrench, B=E (middle of the wrench), F next to the top of the wrench, A (top of the wrench), C (bottom of the wrench)

Total, 110 ohms resistance you would need to the circuit in order to limit the current to 2 amperes.

To limit the current in the circuit to 2 amperes, we can use Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R);

I = V / R

Given;

Operating voltage (V) = 220 volts

Circuit resistance (R) = 55 ohms

Desired current (I_desired) = 2 amperes

We wil rearrange Ohm's Law to solve for the resistance required to achieve the desired current;

R_required = V / I_desired

Substituting the given values, we have;

R_required = 220 V / 2 A

Calculating the division, we find;

R_required = 110 ohms

Therefore, you would need to add an additional resistance of 110 ohms to the circuit in order to limit the current to 2 amperes.

According to Erikson, a coherent conception of the self, made up of goals, values, and beliefs to which a person is solidly committed is called identity.

Identity, according to Erikson, is a "basic organizing principle that evolves continuously throughout the course of a lifetime."

Identity refers to a person's subjective sense of self, which is comprised of experiences, relationships, beliefs, values, and memories. This makes it easier to maintain a consistent self-image throughout time, even as new aspects of who you are emerging or become stronger.

Identity gives one a sense of self-sameness or continuity both within and in relation to others. Identity, which serves as a framework to distinguish between oneself and social engagement, also contributes to uniqueness. Identity, in addition to the aforementioned, contributes to psychosocial development. Adolescents' physical and mental health is also a component of their identity.

The paper should be placed at the focal point of the lens to obtain a sharp image.

The focal point of a lens is the point where parallel rays of light converge or diverge after passing through the lens. Placing the paper at this point ensures that the incoming light rays from the object on the other side of the lens converge precisely onto the paper, resulting in a focused and sharp image.

The distance between the lens and the paper should be equal to the focal length of the lens. The unit of focal length is typically measured in millimeters (mm) or meters (m), depending on the scale of the lens. Therefore, the paper should be positioned at the focal point of the lens to achieve a sharp image, with the distance measured in units of length such as millimeters or meters.

Answer:

Magma from the core

Explanation:

...?

Answer:

V = 0.01(R₁ + R₂)

Explanation:

From Ohm's law, the voltage V across a resistor with resistance R and a current I passing through it is given by

V = IR

If we have two resistances, R₁ and R₂ in series, the total resistance R is the sum of their resistances.

So, R = R₁ + R₂

Now, if the current in the circuit is 0.01 A, the voltage V is

V = IR

V = 0.01R

Substituting R = R₁ + R₂ into the equation for V, we have

V = 0.01(R₁ + R₂)

So, the voltage in two series resistors with current 0.01 A is

V = 0.01(R₁ + R₂)

According to the most recent data from satellites making precise measurements of the properties of the cosmic background radiation (CBR), it has been determined that dark energy makes up approximately 68% of the total energy density of the universe.

This means that dark energy is the dominant force driving the acceleration of the expansion of the universe.

The CBR is the afterglow of the Big Bang, and by analyzing its properties, scientists can learn more about the structure and evolution of the universe. The Planck satellite, launched in 2009, has been instrumental in providing high-precision measurements of the CBR and contributing to our understanding of dark energy.

Despite being the dominant force in the universe, dark energy remains a mystery. Its nature and properties are still largely unknown, but it is thought to be a property of space itself rather than a type of matter or energy. Ongoing research and observations will continue to shed light on this elusive phenomenon and deepen our understanding of the universe as a whole.

Answer:

500 kpa

Explanation:

The pressure exerted by a bullet can be calculated using the formula pressure = force/area. Plugging in the given values, we get:

pressure = 2500 N / 0.005 m^2 = 500,000 N/m^2

Since 1 kilopascal (kPa) = 1000 N/m^2, we can convert the pressure to kPa:

pressure = 500,000 N/m^2 ÷ 1000 = 500 kPa

So the answer is 500 kPa.

(a) To find the tension in the connecting cord with a horizontal force of 2.3 N, identify the forces acting on the system and the horizontal force will be equal to the tension in the cord.

1. Identify the forces acting on the system. There are two forces acting on the system: the horizontal force (2.3 N) and the tension in the cord (T).

2. Since the surface is frictionless and the pulley is massless and frictionless, the horizontal force will be equal to the tension in the cord. Therefore, T = 2.3 N.

So, the tension in the connecting cord is 2.3 N.

(b) To find the largest value of the magnitude of the horizontal force without the cord becoming slack, follow these steps:

1. Identify the forces acting on the system. There are two forces acting on the system: the horizontal force (F) and the tension in the cord (T).
2. In order for the cord to not become slack, the tension in the cord must be greater than or equal to zero. Therefore, T ≥ 0.
3. Since the surface is frictionless and the pulley is massless and frictionless, the horizontal force will be equal to the tension in the cord. Therefore, F = T.
4. Since T ≥ 0, it follows that F ≥ 0.

So, the largest value of the magnitude of the horizontal force without the cord becoming slack is any value greater than or equal to zero.

1. Coefficient of kinetic friction = 0.1.
2. The speed of the mass will be 6.26 m/s right before hitting the floor.


1. To find the coefficient of kinetic friction, we can use the equation of motion. The distance traveled by the block on the ramp is given as 5 meters, and the initial velocity is 10 m/s. Using the equation of motion, we can find the deceleration of the block. Then, using the equation of force, we can find the force of friction acting on the block. Finally, dividing the force of friction by the weight of the block, we get the coefficient of kinetic friction, which is 0.1.

2. In this case, we can use the conservation of mechanical energy to find the velocity of the mass when it hits the floor. The potential energy stored in the spring when it was compressed is equal to the kinetic energy of the mass when it leaves the spring. Using the equation of motion, we can find the distance traveled by the mass on the horizontal surface of the tabletop. Then, using the equation of motion again, we can find the time taken by the mass to reach the floor. Finally, dividing the distance traveled by the time taken, we can find the velocity of the mass, which is 6.26 m/s.
