Answer:
Centripetal force is equal to 31.55 N
Explanation:
We have given mass of the body m = 8 kg
Radius of the circular path r = 10 m
It is given that it makes 1 revolution in 10 seconds
Distance traveled in 10 seconds is equal to 
Velocity is equal to 
We have to find the centripetal force
Centripetal force is equal to 
So centripetal force will be equal to 31.55 N
The direction of current flow is given by an arrow in the electrical circuit.
Several categories are used to categorise electrical circuits. One-way current only flows through a direct-current circuit. As with most residential circuits, an alternating-current circuit is a channel for transmitting electrical current that pulses back and forth numerous times each second.
A battery or generator, a device that provides energy to the charged particles that make up the current, a device that uses current, such as a lamp, an electric motor, or a computer, and the connecting wires or transmission lines make up an electrical circuit.
A source of electrical power, two wires that can transmit current, and a light bulb make up an electrical circuit. Both wires have one end connected to a cell terminal and the other end connected to a light bulb. When the light bulb is turned off, the electrical circuit is disrupted.

Answer:
that technician A is right
Explanation:
The test lights are generally small bulbs that are turned on by the voltage and current flowing through the circuit in analog circuits, these two values are high and can light the bulb. In digital circuits the current is very small in the order of milliamps, so there is not enough power to turn on these lights.
From the above it is seen that technician A is right
Answer:
Explanation:
B- The red horse's average speed was greater than the black horse's average speed.
Red average speed = 1/120 = 0.00833 mi/s
Black average speed = 1/150 = 0.00667 mi/s
we only know about average speed based on the information given. Either horse could have had higher or lower, even negative, instantaneous speed during some phase of the race.
Answer:
Explanation:
2F-F=ma, so F=ma or .17=(13x10-3kg)a then a=13.07m/s2
