Water makes a good coolant because it has a (A)<span> high specific heat. The higher the specific heat, the slower it reaches the point of boiling. Thus, since its specific is very high, then it makes a good coolant because the moment it reaches it lowest point, the transition from cold to hot will be slower.

A good coolant must be able to absorb large amount of heat, must be cheap and easily available. we know that water has high specific heat which means that it can absorb large amount of heat in it. it is also easily available and cheap. This makes water a good coolant. So the correct choice is

a. high specific heat

Earth distance to the Sun is about 40 times the Moon's distance from earth.

<u>Explanation:</u>

  • The Earth's distance from the Sun is about 93 million miles. When it expressed in Km, it is 150 million Km.
  • The Moon's distance from Earth is 238,855 miles. When it is 40 times then it will approximately equal to 93 million miles.
  • The Sun's distance from Venus is 67.237 million miles. The Sun's distance from mercury is 35.832 million miles.

What percentage of the power of the battery is dissipated across the internal resistance and hence is not available to the bulb?
spin [16.1K]

Lets us consider an example:


Suppose a 10 ohm bulb is connected across the terminals of a 10 V

battery having 2ohm internal resistance.

Then total reistance in series we know, R1 + R2 

Thus, R net = 10+ 2 = 12 ohm

The, current across circuit = 10/12= 0.833 A

Now, Power is given by P = i^{2} R \\ \\

Thus, power dissipated across internal resistance, P = 0.83^{2} * 2 = 1.37 Watt

And, total power dissipated =0.83^{2} * 12 = 8.2 watt

Thsu, percentage of pwer not avaible = 1.37/8.2 = 16.70%

Megan walks 1100 m to the left in 330s. What was her average speed in m/s?
Hunter-Best [27]

Answer:

3.33m/s

Explanation:

Speed is the change in distance of a body with respect to time.

Speed = Distance/Time

Given

Distance = 1100m

Time = 330s

Speed = 1100/330

Speed = 3.33m/s

Hence her average speed in m/s is 3.33m/s

A ball is thrown straight up with an initial velocity of 6.4 m/s. It travels for 0.64 seconds, and has a change of position of 2
Naya [18.7K]

Answer:

V = 0.9 m/s

Explanation:

The parameters given are:

Initial velocity U = 6.4 m/s

Time t = 0.64s

Height h = 2.05 m

To find the final velocity, let us use third equation of motion

V^2 = U^2 - 2gH

Since the ball is going upward, g will be negative

Substitute all the parameters into the formula

V^2 = 6.4^2 - 2 × 9.8 × 2.05

V^2 = 40.96 - 40.18

V^2 = 0.78

V = sqrt( 0.78)

V = 0.883 m/ s

V = 0.9 m/ s approximately
