Can you cool a kitchen by leaving the refrigerator door open while the refrigerator is operating? a. No. Since the refrigerator

is operating, the “heat pump” transfers thermal energy from the inside of the refrigerator to the outside of the refrigerator which is presumably in the same room. Since this process is not 100% efficient due to the second law, the average temperature of the room will increase over time. b. No. Since the refrigerator is operating, the “heat pump” transfers thermal energy from the inside of the refrigerator to the outside of the refrigerator which is presumably in the same room. Due to the second law, there will be no change in temperature due to the perfect efficiency of the heat pump.

What affect does a tripling of the net force have upon the acceleration of the object ? Be quantitative
vovikov84 [41]
The formula of net Force is:
F = ma
where m is the mass of the object
a is the acceleration of the object

so if we triple the net force applied to the object:
3F = ma
a = 3F / m

so the acceleration will also be tripled. because from the equation, the force is directly proportional to the acceleration

A pendulum on plant X is 0.25 meters long and the period is 4 seconds. What is “g” on Planet X?
Monica [59]

Answer:

The value of g = 0.6168 m/s².

Explanation:

Given that,

On a planet X,

Length of the pendulum(L) = 0.25 meters,

Time period of the pendulum(T) = 4 seconds.

We have to find the 'g' value on the planet.

The 'g' value on a planet can be found by a pendulum with help of the formula,

T = 2π × \frac{\sqrt{L} }{\sqrt{g} }

From this,  g = 4π² × \frac{L}{T^{2} }

Using the above formula and substituting the values,we get,

g = 0.6168 m/s².

Can someone give me some tips of how to study. I have already tried writing everything in my lesson but it doesn't seem to work
larisa [96]
Highlighter, color coding sections that go together, flash cards, relaxing with someone while they read out questions ( this will help with testing anxiety too). If you get distracted easily use games to study or small sayings instead of the usual white and black sheet of paper.
