Answer:
I believe the answer is B, the paths of the planets follow an elliptical orbit around the sun.
Answer:
Zero
Explanation:
Acceleration is rate of change of velocity..
Answer:These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Explanation:
Static electricity<span> is a </span>buildup<span> of </span>electric<span> charges on objects. Charges </span>build up<span> when negative </span>electrons<span> are transferred from one object to another. The object that gives </span>up electrons<span> becomes positively charged, and the object that accepts the </span>electrons<span> becomes negatively charged. This can </span>happen<span> in several ways</span>
Answer:
261.3 m/s
Explanation:
Mass of bullet=m=15 g=
1 kg=1000g
Mass of block=M=3 kg
d=0.086 m
Total mass =M+m=3+0.015=3.015 kg
K.E at the time strike=Gravitational potential energy at the end of swing
Using g=
Substitute the values
Velocity after collision=V=1.3 m/s
Velocity of block=v'=0
Using conservation law of momentum
Using the formula
