We can reduce the force in collisions by extending the ____ of impact

The magnitude of the net force on the object is 8 N. This is because the force of gravity, which is 17 N, is being opposed by the force of air resistance, which is 9 N. Therefore, the net force is 17 N - 9 N = 8 N.

Force is a push or pull on an object that is caused by an interaction between two objects. It has both magnitude, which is the strength of the interaction, and direction, which is the direction in which the force is being applied.

Net force is the sum of all the forces acting on an object. It is calculated by adding up all the forces that are acting on the object, taking into account their directions. This can be used to calculate the acceleration of an object, as the greater the net force, the greater the acceleration.

The expression for the normal force is

N = mg cos(0)

Substitute 25kg for \(9.8m/s^{2}\)\(m_{c}\) , for, g, and 38° for ∅.

N = (25kg)(9.8m/s²)cos(38°)

= 193.06N

The normal force is the reaction force from the surface of an object. The more you push the surface, the greater the normal force. The frictional force is canceled by the child's weight, so the normal force is the child's weight.

Gravity pulls items down the slide, but another element of physics comes into play friction or resistance. Frictional forces arise from two objects rubbing against each other such as a pine cone and a slide. Friction works against gravity and slows things down the slide.

The normal force acting on the child is 174.56 N

A force is an influence that can change the motion or direction of an object or body. A force can cause an object/ body with mass to change its velocity, i.e., to accelerate.

We have,

The mass of the child, m = 25 kg

Slide's inclination, θ = 38°

The 30 N force at 38 degrees and the child's weight are the forces acting on the child.

The child weighs the following along the vertical component:

Weight = mg × cos(θ)

Weight = 25 × 9.8 × cos(38)

Weight = 193.06

Now, the horizontal component of the 30 N force will be:

F' = 30 × sin(38)

F' = 18.50 N

Therefore, the normal force of the slide acting on the child will be:

F = weight - F'

F = 193.06 - 18.50

F = 174.56 N

So, the normal force acting on the child is 1746.56 N.

Answer:

\(a=18.51\ m/s^2\)

Explanation:

Given that,

Initial speed, u = 0 km/h

Final speed, v = 100 km/h = 27.77 m/s

Time, t = 1.5 s

We need to find the average acceleration of this motorcycle. It is equal to the rate of change of velocity and it is given by :

\(a=\dfrac{v-u}{t}\\\\a=\dfrac{v}{t}\\\\a=\dfrac{27.77\ m}{1.5\ s}\\\\a=18.51\ m/s^2\)

So, the acceleration of the motorcycle is \(18.51\ m/s^2\).

Isaac Newton's discovery of the universal law of gravitation. In fact, it was a groundbreaking scientific achievement that revolutionized the field of physics and laid the foundation for modern astronomy.

In the late 17th century, Newton formulated his law of gravitation after years of experimentation, observation, and mathematical calculations. He realized that the same force that caused apples to fall from trees also governed the movements of the planets in our solar system. This led him to develop his famous equation that described the force of gravity between any two objects in the universe.

Newton's work was widely recognized and celebrated during his lifetime, and his law of gravitation remains one of the most important scientific discoveries in history.

The required Carnot engine performs 1318.31 J of work per cycle.

The Carnot engine is an idealized heat engine that operates between two thermal reservoirs and is the most efficient engine possible for a given set of thermal reservoirs. The efficiency of a Carnot engine is given by the formula:

\(Efficiency = 1 - (T_{low} / T_{high})\)

In this problem, the high-temperature reservoir is at 435 K and the low-temperature reservoir is at 280 K. Therefore, the efficiency of the Carnot engine is:

Efficiency = 1 - (280/435) = 0.3563 or 35.63%

The Carnot engine absorbs 3700 J of heat each cycle. Therefore, the work performed per cycle by the engine is:

Work = Efficiency * Heat absorbed
          = 0.3563 * 3700 J = 1318.31 J

Therefore, the Carnot engine performs 1318.31 J of work per cycle.

Answer:

Gene Sarazen began to win tournaments in 1935 with a new club he had invented that was specialized for sand play. He is hailed as the inventor of the sand wedge.

Explanation:

A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six classical simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular (normal) to its inclined surfaces. The mechanical advantage of a wedge is given by the ratio of the length of its slope to its width.[1][2] Although a short wedge with a wide angle may do a job faster, it requires more force than a long wedge with a narrow angle.

The force is applied on a flat, broad surface. This energy is transported to the pointy, sharp end of the wedge, hence the force is transported.

The wedge simply transports energy and collects it to the pointy end, consequently breaking the item. In this way, much pressure is put on a thin area.

The equivalence principle is a fundamental principle of physics that states that the effects of gravity and acceleration are indistinguishable.

This means that an observer in a closed box cannot determine whether the box is stationary on the surface of the Earth under the influence of gravity or is accelerating in outer space with no gravity.

In other words, the gravitational force and the inertial force are equivalent and cannot be distinguished from each other.

The driver experiences about 0.835 g, g-force during the acceleration. and the car travels about 49.8 meters (163 feet) to hit 60 mph.

What is g-force?

To calculate the g-force experienced by the driver during the acceleration, we need to use the formula:

g-force = acceleration due to gravity / acceleration of the car

The acceleration due to gravity is approximately 9.81 m/s², or 32.2 ft/s².

The acceleration of the car can be calculated by converting the acceleration from 0-60 mph to meters per second squared (m/s²). We can use the following formula to convert:

a = (v_f - v_i) / t

where:

a = acceleration

v_f = final velocity (60 mph in this case, which is 26.8 m/s)

v_i = initial velocity (0 mph in this case, which is 0 m/s)

t = time taken to reach final velocity (2.28 seconds in this case)

Plugging in the values, we get:

a = (26.8 m/s - 0 m/s) / 2.28 s

a ≈ 11.75 m/s²

Now we can calculate the g-force experienced by the driver:

g-force = 9.81 m/s² / 11.75 m/s²

g-force ≈ 0.835 g

Therefore, the driver experiences about 0.835 g during the acceleration.

To calculate the distance traveled by the car to hit 60 mph, we can use the following formula:

d = v_i * t + 0.5 * a * t²

where:

d = distance traveled

v_i = initial velocity (0 mph in this case, which is 0 m/s)

t = time taken to reach final velocity (2.28 seconds in this case)

a = acceleration (11.75 m/s²)

Plugging in the values, we get:

d = 0 m/s * 2.28 s + 0.5 * 11.75 m/s² * (2.28 s)²

d ≈ 49.8 m

Therefore, the car travels about 49.8 meters (163 feet) to hit 60 mph.

The resistance of a circuit that contains two 50.0 Ω resistors connected in series with a 12.0 V battery is 100 Ω. The resistance of the circuit is equal to the sum of the individual resistors when they are connected in series.

In this case, two 50.0 Ω resistors are connected in series, resulting in a total resistance of 100 Ω. Resistance can be defined as the obstruction that electricity faces when it travels through a conductor. The greater the resistance, the less current is allowed to flow through the circuit. The following equation is used to calculate resistance: R = V / IWhere R is resistance, V is voltage, and I is current.

Resistance can also be calculated using Ohm's Law if we know the values of voltage and current. When resistors are connected in series, the total resistance of the circuit is equal to the sum of the individual resistors. This is expressed by the following equation:RT = R1 + R2 + ... + RNWhere RT is the total resistance of the circuit, and R1, R2, and RN are the individual resistors. In this case, the circuit contains two 50.0 Ω resistors connected in series.

One of the properties of a rhombus is that the diagonals bisect each other at 90°

This means AC and BD are perpendicular to each other.

Let us call this intersection point as O

Then AOC forms a triangle with angles 3x - 13, 8x-7 and 90°

Since the sum of 3 angles of a triangle = 180°

(3x - 13) + (8x-7) + 90 = 180

(3x - 13) + (8x-7) = 180 - 90

(3x - 13) + (8x-7)  = 90

3x - 13 + 8x - 7 = 90

3x + 8x - 13 - 7 = 90

11x - 20 = 90

11x = 90 + 20 = 110
