Answer:

$potential \: energy = mgh \\ m = 783 \\ g = 10 \\ h = 164 \\ pe = 783 \times 10 \times 164 \\ = 7830 \times 164 \\ = 1284120 \: joule \\ thank \: you$

Explanation:

$\sf \: Mass \: of \: the \: body: 783\: kg$

$\sf \: Acceleration \: due \: to \: gravity : 10$

$\sf \: Height : 164 \: metres$

$\sf\longmapsto \: 783 \times 10 \times 164$

$\sf\longmapsto 7830 \times 164$

$\sf\longmapsto 1284120\:$

$\sf\longmapsto 1284120 \:Joule\:$

An object acted on by three forces moves with constant velocity. One force acting on the object is in the positive xx direction

Rudik [331]

Answer with Explanation:

We are given that

$F_1=6.9 N$

$F_2=4.5 N$

We have to find the direction and magnitude of the third force acting on the object.

Resultant force,F= $\sqrt{F^2_1+F^2_2}$

$F=\sqrt{(6.9)^2+(4.5)^2}=8.24 N$

The object moves with constant velocity .Therefore, net force on object is equal to zero

So,Third force, $F_3=F=8.24 N$

Direction, $\theta=tan^{-1}(\frac{F_2}{F_1})$

$\theta=tan^{-1}(\frac{4.5}{6.9})=33.02^{\circ}$

Angle lies in second quadrant because the direction of third force is opposite to the direction of the resultant force of F1 and F2.

Therefore, $\theta=\pi-\theta=180-33.02=146.98^{\circ}$

how can changing the kinetic energy of an object cause energy to be transferred to or from the object

melisa1 [442]

Kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. For the blue ball to move to the position of the green ball, energy must be given to the blue ball.

A mass m neutron has elastic collision with a mass m'

hoa [83]

Answer:

The neutron loses all of its kinetic energy to nucleus.

Explanation:

Given:

Mass of neutron is 'm' and mass of nucleus is 'm'.

The type of collision is elastic collision.

In elastic collision, there is no loss in kinetic energy of the system. So, total kinetic energy is conserved. Also, the total momentum of the system is conserved.

Here, the nucleus is still. So, its initial kinetic energy is 0. So, the total initial kinetic energy will be equal to kinetic energy of the neutron only.

Now, final kinetic energy of the system will be equal to the initial kinetic energy.

Now, as the nucleus was at rest initially, so the final kinetic energy of the nucleus will be equal to the initial kinetic energy of the neutron.

Thus, all the kinetic energy of the neutron will be transferred to the nucleus and the neutron will come to rest after collision.

Therefore, the neutron loses all of its kinetic energy to nucleus.
