Vaselesa [24]3 years ago

As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the direction of the object's motion, the velocity vector is directed tangent to the circle as well.

An electric drill operating at 120 volts draws a current of 3 Amperes. What is the total amount of electrical energy used by the
Liono4ka [1.6K]
<h3><u>Answer;</u></h3>

= 21600 Joules or 21.6 Kilo joules

<h3><u>Explanation;</u></h3>

Electrical energy is given by the formula  = VIt ;

where V is the voltage in volts, I is the current in Amperes, and t is time in seconds.

Voltage = 120 volts

Current = 3 amperes

Time = 60 seconds or 1 minute

Therefore;

Electrical energy = 120 × 3 × 60

                            <u> = 21600 Joules or 21.6 Kilo joules</u>

1. A race car moves along a circular track of radius 100m at a velocity of 25m/s. (a) What is
goldenfox [79]

Given :

A race car moves along a circular track of radius 100m at a velocity of 25m/s.

To Find :

(a) What is  the time taken to complete one lap of the circular track.

(b) What is the time taken for 10  laps.

Solution :

Circumference of circular track,

C = 2\pi r\\\\C = 2\times \pi \times 100\ m\\\\C = 628.32 \ m

a) Time taken to complete one lap is :

t= \dfrac{628.32}{25}\ s\\\\t =25.13 \ s

b) Time taken to complete 10 laps is :

t_{10} = 10\times t\\\\t_{10} = 10\times 25.13\ s\\\\t_{10} = 251.3\ s

Hence, this is the required solution.
