Answer:
Acceleration will be change at every instant of time
Explanation:
We have given that speed of the car at curve round is constant
We know that speed is scalier quantity which does nit depend on the direction of motion.
Velocity is vector quantity which depends on the direction of motion
As on curve round direction of motion is always changes so velocity is also changes and acceleration is rate of change of velocity
So acceleration of the car will also change.
The velocity of the combination of Jackie and the bicycle is 3.328 m/s.
Explanation:
From the given data the constant kinetic energy is 3.6 J. The mass of combination is 0.65 kg. To find the velocity of the combination of Jackie and the bicycle the formula is
KE = 0.5 x mv2.
To find velocity,
V2=ke/(0.5×m)
V=
v= 3.6/(0.5×0.65)
=
v= 3.328 m/s
Hence, the velocity of the combination of Jackie and the bicycle is 3.328m/s.
Transformer. Its an electrical device that uses electromagnetic induction to pass an alternating current (AC) signal from one electric circuit to another, often changing the voltage and electrical current
If you mean beneficial in improving cardiovascular endurance then the best sports would be swimming, running, basketball, rowing and squash.
Answer:
Explanation:
The force is defined as the negative of the derivative of the potential energy:
If we use the potential energy function given in this problem:
and we calculate the force, we get:
So, the force is
