Answer:

When an object changes speed (increases/decreases) it results in acceleration/de acceleration, its velocity also changes.

Explanation:

Acceleration is the rate of change in velocity.An object can accelerate when speed increases, decreases or direction changes. All these instances involves a change in velocity.Velocity is a vector quantity thus it has magnitude and the direction.Acceleration due to change in direction is centripetal acceleration.The expression for finding acceleration is;

a=change in velocity/change in time

a=Δv/Δt in m/s²

Answer : The average power delivered to the circuit is, 42.6 watt

Explanation :

The relation between power, voltage and current is:

$P=I\times V$

where,

P = power of circuit = ?

I = current = 6.0 A

V = voltage = 7.1 V

Now put all the given values in the above formula, we get the average power delivered to the circuit.

$P=6.0A\times 7.1V$

$P=42.6watt$

Thus, the average power delivered to the circuit is, 42.6 watt

1. Define robbery, burglary, safe burglary, and theft.

neonofarm [45]

Answer:

So if a person breaks a window to get into the house or break open your cupboard to steal, it is considered burglary. Usually, an HPP covers burglary but not theft. Theft would mean the person committing the crime had access to the house or its valuables.

A Ferris wheel with a 15-m radius makes three complete revolutions in one minute about its horizontal axis. What is the magnitud

Kay [80]

Answer:

$1.48 m/s^2$ , upward

Explanation:

The passenger on the wheel experiences a centripetal acceleration, which is the one that keeps him in a circular motion.

The direction of this acceleration is always towards the centre of the circular trajectory: so when the passenger is at the lowest point of the ride, the acceleration is upward.

Concerning the magnitude, it is given by

$a=\omega^2 r$

where

$\omega$ is the angular velocity

r = 15 m is the radius

We need to find the angular velocity; we know that the wheel completes 3 revolutions in one minute. Each revolution corresponds to an angle of $2\pi$ rad, so the total angular displacement is
