If the elevator's speed is constant (in ANY direction) and you can't see out of it, then there's NO measurement you can make inside that will tell you that it's moving. Any weight you measure is normal.
Answer:
s₁ = 4.67 m from car A
Explanation:
Since, the cars are moving at a constant speed. Hence, we will apply the equation for uniform motion here:
s = vt
where,
s = distance covered
v = velocity
t = time taken
For Car A:
s₁ = (1.4 m/s)t
For Car B:
s₂ = (2.2 m/s)t
Because the time will be same at the collision. At collision the distance covered by Car A and Car B must be 12 m altogether. Hence:
s₁ + s₂ = 12 m
using values:
(1.4 m/s)t + (2.2 m/s)t = 12 m
t = 12 m/3.6 m/s
t = 3.333 s
Substitute this in the equation of s₁:
s₁ = (1.4 m/s)(3.33 s)
<u>s₁ = 4.67 m from car A</u>
Answer:

Explanation:
As we know that it will have constant torque on it
so the acceleration of the ball will be constant so here we can say that we can use kinematics equation



so we have


now we know that



so we know that

here we know that
diameter = 0.72 m
so radius (R) = 0.36 m


Answer: i could prolly answer if it made more sense. which of the following where?
Astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
<h3>Who is an astronaut?</h3>
It should be noted that an astronaut simply means an individual who is trained to travel in spacecrafts.
In this case, astronomers suspected an eighth planet beyond Uranus because of the irregularities in the motion of Uranus suggested that gravity from another planet was affecting it.
In mid-1800s, astronomers used the orbits of most asteroids to predict where a planet would have to be.
