Answer:
0.66c
Explanation:
Use length contraction equation:
L = L₀ √(1 − (v²/c²))
where L is the contracted length,
L₀ is the length at 0 velocity,
v is the velocity,
and c is the speed of light.
900 = 1200 √(1 − (v²/c²))
3/4 = √(1 − (v²/c²))
9/16 = 1 − (v²/c²)
v²/c² = 7/16
v = ¼√7 c
v ≈ 0.66 c
Answer:
F = 2.6692 x 10⁻⁹ N
Explanation:
Given,
The mass of the rock, m = 10 kg
The mass of the boulder, M = 100 kg
The distance between them, d = 5 m
The gravitational force between the two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them. It is given by the formula
<em> F = GMm/d² newton</em>
Where,
G - Universal gravitational constant
Substituting the given values,
F = 6.673 x 10⁻¹¹ x 100 x 10 / 5²
F = 2.6692 X 10⁻⁹ N
Hence, the force between the two bodies is, F = 2.6692 X 10⁻⁹ N
Answer:
83.055 m
Explanation:
According to the given scenario, the calculation of skid distance is shown below:-
Where
u = 11.3
v = 0
t = 14.7
Now placing these values to the above formula,
So,
= 83.055 m
Therefore for computing the skid distance we simply applied the above formula i.e by considering the all items given in the question

Explanation:

if your vehicle begins to slide or skid in the rear, you should steer in the direction that the rear is sliding to.
<h3>What should you do if the rear end of the vehicle starts to slide or skid?</h3>
In the case above, a person need to Look as well as steer in the direction that the person want the front of the vehicle to go.
Note that in the case above;
Do stay way from the brake pedal and never apply the brakes.
- Steer in the the same direction as the rear of the vehicle that is known to be sliding. This will give room for the vehicle to go straight instead of going sideways.
- Then make sure to get ready to steer in the opposite direction if the vehicle is one that begins swerving in the other direction.
Therefore, if your vehicle begins to slide or skid in the rear, you should steer in the direction that the rear is sliding to.
