Answer:
9.21954 m/s
54 m/s²
Angle is zero
Explanation:
r = Radius of arm = 1.5 m
= Angular velocity = 6 rad/s
The horizontal component of speed is given by
The vertical component of speed is given by
The resultant of the two components will give us the velocity of hammer with respect to the ground
The velocity of hammer relative to the ground is 9.21954 m/s
Acceleration in the vertical component is zero
Net acceleration is given by
Net acceleration is 54 m/s²
As the acceleration is towards the center the angle is zero.
Answer:
Time= 1/frequency
=1/100
=0.01
Explanation:
Answer: The resultant displacement vector is 5.6km
Answer:
0,6
Explanation:
from the picture there are 10 dots. It means that the time needed to make these dot is
10/50 * 1 sec = 0.2 sec
the length (or we can say distance) of 10 dots are 12 cm. we must convert to meter so it become 0.12 m
v = d/t = 0.12/0.2 = 0.6 m/s
The flow of an alternating current switches direction when a generator's terminals change its charge is true regarding current in an external circuit
<u>Explanation:
</u>
Two types of currents, one of them is direct current (DC), constant charging current in one direction. The current in the DC circuits shifts in a constant direction. The amount of electricity can vary, but it always flows from one point to another.
Next is alternating current (AC), the movement of the electric charge periodically changes direction. It is the form most often provided to enterprises and households. The usual form of AC wave is the sine wave. Some applications use different wave-forms, e.g. B. triangular or square waves.
