Answer:
4 kg
Explanation:
Acceleration = 4 m/s^2
Force = 16 N
Force = mass * acceleration
mass = force / acceleration
mass = 16 / 4
mass = 4 kg
Answer:
boiling and melting!
Explanation:
These do not make any changes chemically to the substance.
Hope this helps!
Answer:
5 N
Explanation:
The bucket is moving at a constant speed of 2m/s Therefore F=ma is 0 N for this to be correct the magnitude of the force exerted by the rope must be equal to the weight of the bucket which is 5 N
Ohms law = v= Ir
V= 0.02 x 4000 = 80v
Answer:
move at constant velocity.
Explanation:
Newton's first law (also known as law of inertia) states that:
"when the net force acting on an object is zero, the object will keep its state of rest or if it is moving, it will continue moving at constant velocity".
In the case of the probe, friction in deep space is negligible, therefore when the engine is shut down, there are no more forces acting on the probe: the net force therefore will be zero, so the probe will move at constant velocity.
