Answer:

64.20m

Explanation:

As we can see from the image I have attached below, the route that the chipanzee makes forms a right triangle. In this case, the shortest distance is represented by x in the image, which is the hypotenuse. To find this value we use the Pythagorean theorem which is the following.

\(a^{2} +b^{2} = c^{2}\)

where a and b are the length of the two sides and c is the length of the hypotenuse (x). Therefore, we can plug in the values of the image and solve for x

\(51^{2} +39^{2} =x^{2}\)

2,601 + 1,521 = \(x^{2}\)

4,122 = \(x^{2}\)   ... square root both sides

64.20 = x

Finally, we see that the shortest distance is 64.20m

The most logical conclusion to make in light of the facts available is that the electric field is directed to the left. This conclusion may be drawn from the fact that a negative test charge, which is attracted to positive charges and repels other negative test charges, feels a force to the right.

The force applied to the negative test charge suggests the presence of positive charges in the electric field, indicating that the field lines begin with positive charges and end on negative charges since opposing charges attract.

The assumption that electric field lines originate from positive charges and end on negative charges is supported by this deduction. As a result, in this situation, the electric field is directed leftward.

To better understand crash dynamics we have to look at "the laws of motion."

The laws of motion

The laws of motion were introduced by Sir Isaac Newton in 1687 in his book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), which defined the laws of motion, or three fundamental laws that govern the movement of bodies. The laws of motion, according to Newton, govern the motion of an object or a system of objects that interact.

It defines the concepts of force and mass, and the fundamental dynamics of motion.The following are the laws of motion:Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. The velocity of an object changes proportional to the force applied to it, and the acceleration of an object is proportional to both its force and its mass. For every action, there is an equal and opposite reaction.

Therefore, these laws are necessary to fully grasp crash dynamics because they explain how objects respond to outside forces that cause them to accelerate or decelerate.

Explanation:

This is because, nuclear forces are short range forces.

The protons and neutrons are collectively called nucleons and they are found in the nucleus of an atom. These nucleons are held together by a strong attractive force called the nuclear force.

When atoms combine, they are held together by forces determined by electrons in the outermost shell. The influence of the nuclear force does not extend beyond the nucleus because they are short range forces.

Hence, we not consider the strong nuclear force when we describe the forces between atoms.

What conclusion does the student most likely make based

on this data?

The rank of the forces in order of increasing magnitude is Fg < FB < FA.

option D is the correct answer.

The net force on an elevator moving upwards is determined by the force of gravity acting downwards and the normal force of the elevator acting upwards.

That is, the two forces acting on a person when he is moving in an elevator are:

When the two forces are of equal magnitude, the elevator will be static or moving with constant velocity.

When the magnitude of the two force are unequal, then the elevator will be accelerating upward or downward.

Since the elevator is moving upwards, it implies that the normal force is greater than the force of gravity acting downwards.

The box at the bottom will feel much heavier due to the weight of box and gravity acting downwards.

FA = FB + Fg

Thus, the force exerted on box A is the greatest, followed by the force on box B and then, the smallest is force of gravity.

To find the net charge on the sphere using electric flux, we can use the formula:  

Φ = Q/ε0

Where Φ is the electric flux, Q is the charge, and ε0 is the permittivity of free space.  

Given that the electric field 20 cm from the center of the sphere is N/C and points radially inwards, we can use the formula for electric field due to a charged sphere to find the charge on the sphere:

E = kQ/r^2  

Where E is the electric field, k is Coulomb's constant, Q is the charge, and r is the distance from the center of the sphere.  

Substituting the given values, we get:  

20 = (1/4πε0)(Q)/(0.2)^2  

Solving for Q, we get:  

Q = (20)(0.2)^2(4πε0)  

Q = 0.64πε0 C  

Now, substituting this value of Q in the formula for electric flux, we get:  Φ = Q/ε0 = (0.64πε0)/(ε0) = 0.64π C  

Therefore, the net charge on the sphere is 0.64π C.

The angular speed of the merry-go-round reduced more as the sandbag is

placed further from the axis than increasing the mass of the sandbag.

The rank from largest to smallest angular speed is presented as follows;

[m = 10 kg, r = 0.25·R]

              \({}\) ⇩

[m = 20 kg, r = 0.25·R]

              \({}\) ⇩

[m = 10 kg, r = 0.5·R]

              \({}\) ⇩

[m = 10 kg, r = 0.5·R] = [m = 40 kg, r = 0.25·R]

              \({}\) ⇩

[m = 10 kg, r = 1.0·R]

Reasons:

The given combination in the question as obtained from a similar question online are;

1: m = 20 kg, r = 0.25·R

2: m = 10 kg, r = 1.0·R

3: m = 10 kg, r = 0.25·R

4: m = 15 kg, r = 0.75·R

5: m = 10 kg, r = 0.5·R

6: m = 40 kg, r = 0.25·R

According to the principle of conservation of angular momentum, we have;

\(I_i \cdot \omega _i = I_f \cdot \omega _f\)

The moment of inertia of the merry-go-round, \(I_m\) = 0.5·M·R²

Moment of inertia of the sandbag = m·r²

Therefore;

0.5·M·R²·\(\omega _i\) = (0.5·M·R² + m·r²)·\(\omega _f\)

Given that 0.5·M·R²·\(\omega _i\) is constant, as the value of  m·r² increases, the value of \(\omega _f\) decreases.

The values of m·r² for each combination are;

Combination 1: m = 20 kg, r = 0.25·R; m·r² = 1.25·R²

Combination 2: m = 10 kg, r = 1.0·R; m·r² = 10·R²

Combination 3: m = 10 kg, r = 0.25·R; m·r² = 0.625·R²

Combination 4: m = 15 kg, r = 0.75·R; m·r² = 8.4375·R²

Combination 5: m = 10 kg, r = 0.5·R; m·r² = 2.5·R²

Combination 6: m = 40 kg, r = 0.25·R; m·r² = 2.5·R²

Therefore, the rank from largest to smallest angular speed is as follows;

Combination 3 > Combination 1 > Combination 5 = Combination 6 >

Combination 2

Which gives;

[m = 10 kg, r = 0.25·R] > [m = 20 kg, r = 0.25·R] > [m = 10 kg, r = 0.5·R] > [m =

10 kg, r = 0.5·R] = [m = 40 kg, r = 0.25·R] > [m = 10 kg, r = 1.0·R].

Changing the green sum of forces arrow involves manipulating applied forces, frictional forces, and normal forces, allowing for adjustments in magnitude and direction through various means.

To change the green sum of forces arrow, you can employ the following three strategies:

Adjusting Applied Forces: By modifying the magnitude or direction of the applied forces, you can alter the green sum of forces arrow. If the applied forces are increased or directed in a different way, the green sum of forces arrow will change accordingly. For instance, increasing the magnitude of a pushing force will result in a larger green sum of forces arrow in that direction.

Modifying Frictional Forces: Frictional forces play a crucial role in determining the green sum of forces. By changing the coefficient of friction or applying lubricants, you can affect the magnitude of frictional forces acting on an object. Reducing friction will decrease the green sum of forces arrow, while increasing friction will have the opposite effect.

Varying Normal Forces: The green sum of forces arrow can be influenced by adjusting the normal forces acting on an object. Normal forces are perpendicular to the surface and counteract the weight of an object. By changing the angle or surface on which an object rests, you can modify the normal forces. This alteration will subsequently impact the green sum of forces arrow.

Explanation:

Given that,

Speed of a hare, v = 15 m/s

Speed of a turbocharged tortoise, v' = 3 m/s

The hare in a 250 meter race

Let the Hare takes time t. It can be calculated as follows :

\(t=\dfrac{250}{15}=16.67\ s\)

Let a turbocharged tortoise takes t'. It can be calulated as follows :

\(t'=\dfrac{250}{3}= 83.33\ s\)

To tie the race, required time is given by :

\(\Delta t = t'-t\\\\=83.33-16.67\\\\=66.66\ s\\\\\approx 66.7\ s\)

B . a heat transfer caused

The transformation of energy from one form to another is the process where energy is converted from one form to another while the total amount of energy remains constant. This means that energy cannot be created or destroyed; it can only be transformed from one form to another.

One example of energy transformation is a light bulb. When a light bulb is switched on, electrical energy is transformed into light energy and heat energy. The electrical energy is transformed into light energy by the light bulb's filament, which heats up and emits light. At the same time, some of the electrical energy is transformed into heat energy, which is dissipated into the surrounding air. The total amount of energy is conserved, but it is transformed from electrical energy to light energy and heat energy.

Another example of energy transformation is a roller coaster ride. When a roller coaster is released from its starting point, its potential energy is transformed into kinetic energy as it moves downhill. As the roller coaster moves uphill, its kinetic energy is transformed back into potential energy. At the bottom of the hill, the kinetic energy is at its maximum, and the potential energy is at its minimum. At the top of the hill, the potential energy is at its maximum, and the kinetic energy is at its minimum. Again, the total amount of energy is conserved, but it is transformed from potential energy to kinetic energy and back again.

Answer:

v₂ = -3.42 m/s

Explanation:

Given that,

Mass of an object, m₁ = 3.6 kg

Initial speed of this object is, u₁ = +6.5 m/s (positive for right)

Mass of another object, m₂ = 5 kg

Initial velocity of this object, u₂ = -4 m/s (negative for left)

Fina velocity of object 1, v₁ = 5.7 m/s

We need to find the final velocity of object 2 i.e. 5 kg object.

It is a concept based on the conservation of momentum. Using the conservation of momentum as follows :

\(m_1u_1+m_2u_2=m_1v_1+m_2v_2\)

v₂ is the final velocity of 5 kg object.

Putting all the values to find it.

\(v_2=\dfrac{m_1u_1+m_2u_2-m_1v_1}{m_2}\\\\v_2=\dfrac{3.6(6.5)+5(-4)-3.6(5.7)}{5}\\\\v_2=-3.42\ m/s\)

So, the final velocity of the object 2 is 3.42 m/s and it is towards left.
