Answer:
An object's acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant - if its direction changes.
Explanation:
Answer:
Well,
Explanation:
In a wave, energy is transported without the transport of water. Basically, a wave can be described as a disturbance that travels through a medium, transporting energy from one location to another location without transporting matter.
Answer:
a) (Positive), b) . The collision is not perfectly elastic.
Explanation:
a) The collision can be described by the Principle of Momentum Conservation and Principle of Energy Conservation:
The final velocity of the rock is:
b) The coefficient of restitution is the best criterion to distinguish elastic collsions from inelastic collisions, such criterion is the ratio of final energy of the system to initial energy of the system:
The collision is not perfectly elastic.
Answer :
0.5 Ω
Explanation:
The following data were obtained from the question:
Voltage (V) = 7.2 V
Current (I) = 14.4 A
Resistance (R) =..?
The resistance of the motor can be obtained by applying the ohm's law equation as shown below:
V = IR
7.2 = 14.4 × R
Divide both side by 14.4
R = 7.2/14.4
R = 0.5 Ω
Therefore, the resistance is 0.5 Ω
