30N

Explanation:

Given parameters:

Mass of object = 15kg

Acceleration = 2m/s

Unknown:

Force = ?

Solution:

Force is given as the product of mass and acceleration:

F = m x a

m is the mass

a is the acceleration

Inputting the parameters:

F = 15 x 2 = 30N

The unit of force is newtons, N .

A refrigerator receives 240 V of electricity. If it uses 32 A of current, what is the resistance of the refrigerator?

Leokris [45]

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the Concept of the Ohms Law,

According to the Ohms law,

V = I*R, where, V = Voltage, I = Current, R = resistance,

so here given as, V = 240 V, I = 32 A,

so we get as, R = 240/32

R = 7.5 ohms,

===> The resistant R is ==> 7.5 ohms.

A car generates 2,552 N and weighs 2,250 pounds. what is the rate of acceleration

Lilit [14]

Ans: a = 2.50 m/s^2

Explanation:
First convert the mass in its standard unit i.e. kilogram(kg):
2250 lbs = 1020.583kg

Next use Newton's Second law:
F = ma

Where F = 2552N
m = 1020.583kg

=> a = (2552/1020.583)
a = 2.50 m/s^2

Describe how the measurements of the required quantities are carried out

jeyben [28]

The measurement of the required quantities are carried out using the

standard tools.

<h3>Measurement</h3>

Measurement involves measuring the quantity an object or a body has.

These are done by the standard tools used for different types of quantities.

Examples include:

Tape rule which is used to measure the length

Beam balance which is used to measure the mass etc.

They normally have standard readings which helps to get accurate results

which is reproducible in all parts of the world.

A roller coaster car crosses the top of a circular loop-the-loop at twice the critical speed. Part A What is the ratio of the no

4vir4ik [10]

Answer:

n/(FG) = 3.

Explanation:

<u>At the top of the loop-the-loop, the normal force is directed downwards</u> as well as the weight of the car. So, the total net force of the car is

$F_{net} = N + mg$
