Answer:
Speed and direction.
Explanation:
When an object accelerates, its velocity changes. Velocity is often thought of as an object's speed with a direction. Thus, objects accelerating are either speeding up, slowing down or changing directions.
First, lets correct your concept. Momentum is still conserved in the system. the ball is falling towards th earth and the earth is also accelerating towards the ball. the forces betwwen the earth and the ball are the same by Newton's third law. but the rate of acceleration of the earth is neglectable seemingly to have no momentum, beacuse the earth has higher mass than the ball by F=ma. Therefore momentum is still conserved.
Answer:
Magnetic field, B = 0.05 T
Explanation:
It is given that,
In magnetic force on a current carrying wire" experiment using the data for force (y-axis, in Newton) versus length in meters, someone obtained a linear curve fit count
y = 0.1 x + 2
Where,
x is in meters
and y is in newtons
Slope of the equation,
Magnetic force is given by,
So, the strength of the magnetic field is 0.05 T. Hence, this is the required solution.
Answer:
∆p=(m2v)kg.m/s
Explanation:
∆p=mv where v=2v. hence ∆p=m2v
Explanation:
when an object speeds up,it has positive acceleration.
