Gnesinka [82]

Nuclear fusion occurs in the core area or center of the Sun. Here, temperatures are around 15,000,000°C. Gravity pulls all of the mass of the Sun inwards, creating pressure so intense that nuclear reactions take place. The nuclei of hydrogen atoms smash together and fuse to form larger atoms such as helium nuclei. Hope this helps!! :)

1) They are able to balance the torques due to gravity.

The torque is equal fo Force * lever arm.

The force downward is due to gravity, Force = mass*gravity.

Then the heavier student will produce a bigger force downgar and he/she shall shorten the lever arm of his/her side, by placing himself closer to the rotation axis, than the lighter student.

Ksenya-84 [330]

Answer:

Part a)

$d = 23.94 m$

Part b)

$\theta = 110 degree$

Explanation:

Part a)

As we know that initially the position vector is r

then the same magnitude position vector is rotated by 40 degree angle

so displacement magnitude is the magnitude of change in position vector

so it is given as

$d = \sqrt{r_1^2 + r_2^2 + 2r_1r_2cos(180-\theta)}$

$r_1 = r_2 = 35 m$

$d = \sqrt{35^2 + 35^2 -2(35)(35)cos40}$

$d = 23.94 m$

Part b)

now we need to find the direction of the displacement vector

so let say it makes an angle with x axis so we have

$tan\theta = \frac{rsin\phi}{r - rcos\phi}$

$tan\theta = \frac{sin 40}{1 - cos40}$

$\theta = 110 degree$

Temka [501]

Answer:

F=ma is the relationship where, F is force, m is mass and a is acceleration.

Newton's second law states that the unbalanced force applied to the object accelerates the object which is directly proportional to the force and inversely to the mass.

If we apply force to a toy car then It will accelerate.

This is how Newton's second law of motion is verified.
