Answer:
Planet will crash on to the Sun if the tangential velocity becomes zero and Rocket should be fired from Earth's orbit is at 30 m/s and in opposite direction to the Earth orbits the Sun
Explanation:
The orbital velocity of the Earth about the sun is 30 km/s. If we shoot a rocket with 30 km/s with respect to Earth in the opposite direction. Then the two velocity vectors cancel. The resultant velocity would be zero with respect to the Sun. resulting velocity is called as tangential velocity.
Planet will crash on to the Sun if the tangential velocity becomes zero and Rocket should be fired from Earth's orbit is at 30 m/s and in opposite direction to the Earth orbits the Sun
Answer:
Matching of Part A with Part B
Rutherford ------------ discovered proton nucleus
Bohr----------------------postulated the quantum atom
Dalton-------------------Father of atomic theory
Chadwick --------------discovery of neutron
J.J. Thomson----------discovered the electrons
hence , the matching will be
2 -- d
3 -- e
4 -- b
5 -- a
6 -- c
Answer:
<h3>The answer is 8.2 kg</h3>
Explanation:
The mass of the object can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>8.2 kg</h3>
