Answer:

The exerting force by the person is 294 N.

(3) is correct option.

Explanation:

Given that,

Mass of crate = 30 kg

Normal force = 150 N

When a person is lifting a crate then the crate does not contact the floor

So, the normal force is zero.

We need to calculate the exerting force by the person

Using formula of force

F = ma

F=30\times9.8

F=294\ N

Hence, The exerting force by the person is 294 N.

Which of the following represent units of an electric field? select all that apply
zimovet [89]

Answer:

Volts/Meter

Newtons/Coulomb

Explanation:

Volts/ Meter and Newtons/Coulomb both are same and the units of Electric field intensity or electric field strength.

Electric field strength E is the force per unit charge. It is measured in Newton/Coulomb in SI unit. It is a vector quantity directed in the direction of force.

Mathematically,

           Electric field strength = Force/Charge

                                           E = F / q₀

                                               = Newton / Coulomb = NC⁻¹             1

We know that

                         Newton = Joule/meter            2

Also

                           Volt = Joule/Coulomb             3

So put 3 in 2 we get

                          Newton = (Volt Coulomb)/meter       put in 1

   

                            E =  (Volt Coulomb)/(meter Coulomb)

                               = Volt / meter

Hence

                  Newton / Coulomb = Volt / meter

20 quantities and classified them in vector and scaler quantities​
ss7ja [257]

Answer:

A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight.

A jet plane flying 600 m/s experiences an acceleration of 4g when pulling out of the dive. What is the radius of curvature of th
Gnoma [55]

Answer:

91.84 m/s²

Explanation:

velocity, v = 600 m/s

acceleration, a = 4 g = 4 x 9.8 = 39.2 m/s^2

Let the radius of the loop is r.

he experiences a centripetal force.

centripetal acceleration,

a = v² / r

39.2 x r = 600 x 600

r = 3600 / 39.2

r = 91.84 m/s²

Thus, the radius of the loop is 91.84 m/s².
