Physics
1 answer:
zzz [600]3 years ago
3 0

Answer:

800W

Explanation:

Given the following data;

Voltage = 230 V

Model = VSO Ha

Power = 800 W

Power is calculated by the multiplication of voltage and current flowing through an electric circuit.

Mathematically, power is given by the formula;

Power = current * voltage

The S.I unit for power is Watts and it is a measure of the energy consumption of an electronic device.

a bowling ball rolled with a force of 15N accelerates at a rate of 5 m/sec^2 a second ball rolled with the same force accelerate
hammer [34]

Answer:

3

3.75

Explanation:

First ball

<em><u>Givens</u></em>

a = 5m/s^2

m = ??

F = 15N

<em><u>Formula</u></em>

F = m*a

<em><u>Solution</u></em>

15 = m * 5

15/5 = m

m = 3 kg

Second ball

<em><u>Givens</u></em>

a = 4m/s^2

m = ??

F = 15N

<em><u>Formula</u></em>

F = m*a

<em><u>Solution</u></em>

15 = m * 4

15/4 = m

m = 3.75 kg

A ball is spun around in circular motion such that its frequency is 10 Hz.
Scilla [17]

Answer:

a = 0.1 s b. 10 s

Explanation:

Given that,

The frequency in circular motion, f = 10 Hz

(a) Let T is the period of itsrotation. We know that,

T = 1/f

So,

T = 1/10

= 0.1 s

(b) Frequency is number of rotations per unit time. So,

t=\dfrac{n}{f}\\\\t=\dfrac{100}{10}\\\\t=10\ s

Hence, this is the required solution.
