Answer:
a) horizontal range s=277671.77 m
b) time the shell is in motion 301.143 s
Explanation:
Is a parabolic movement so the velocity have two components:
°
Both the effects (l<span>engthening of the transmitted signal's wavelength and decrease in its frequency) indicates that the object is moving away from the observer, and this phenomenon is called Doppler effect.
In fact, when the object is moving away from the observer, the relative distance between two consecutive crests of the wave emitted by the object increases to the observer eyes, since he's moving away. This means that the wavelength appears larger, and since the frequency is inversely proportional to the wavelength, the frequency appears smaller.</span>
Answer:
Magnitude of kinetic force is the product of the normal force and the coefficient of kinetic friction.
Explanation:
The kinetic frictional force is the force which is experienced in the moving surfaces of bodies.The magnitude of the force is affected by the coefficient of kinetic friction between the material of two bodies in contact. Mathematically, it is expressed as;
Fk=μk*η
where;
- Fk=force of kinetic friction
- μk=coefficient of kinetic friction
- η=normal force
Answer:
The solar cells transfer light energy to thermal energy.
When the battery is being charged up, chemical energy is transferred to electrical energy.
The motor is designed to transfer potential energy to kinetic energy.
