Answer:B

Explanation:

.03 of an hr is 2 mins and if it takes 2 mins to drive 4 miles enter it in pace calulator you are going 120mph so the closest to 120 is 133mph

krok68 [10]

Answer:

it is essential that the charge on the plates are of the same magnitude, but in the opposite direction

Explanation:

The configuration of parallel plates is called a capacitor and is widely used to create constant electric fields inside.

 To obtain this field it is essential that the charge on the plates are of the same magnitude, but in the opposite direction

This is so that the fields created by each plate can be added inside and subtracted from the outside of the plates

Why is the force of gravity on your body weaker on the Moon than on the Earth?
andrezito [222]

Answer:

The moon’s gravity is weaker than the earth gravity due to the smaller in size as compared to the earth. As there is no atmosphere present on the moon gravity, so there are fewer chances of withstanding temperature.

To sterilize a 53.0 g glass baby bottle, we must raise its temperature from 25.0°C to 92.0°C. How much heat transfer (in J) is r
Stella [2.4K]

The heat energy required is 2983 J

Explanation:

When an amount of energy Q is supplied to a certain sample of substance of mass m, the temperature of the substance increases by an amount of \Delta T according to the equation :

Q=mC_s \Delta T

where

Q is the heat supplied

m is the mass of the object

C_s is the specific heat capacity of the substance

\Delta T is the change in temperature

For the glass bottle in this problem:

m=53.0 g

\Delta T = 92.0 - 25.0 =67.0^{\circ}C is the change in temperature

C_s = 0.84 J/g^{\circ}C is the specific heat of glass

Substituting into the equation, we find

Q=(53.0)(0.84)(67)=2983 J
