Answer:
13.07m/s2 down
Explanation:
I think the equation would be
Fnet/m=a
since tension is the only force mensioned that means that
170N/13.0kg=13.07 m/s2 down
acceleration is down

How does Density depend on the type of object being measured ?
Answer:
ways to exaplined
Explanation:
Density is calculated by
dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples' volume.

Answer:
Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy
Explanation:
Coal is formed from the fossil fuel that lie deep beneath the earth crust . These fossil fuels are dead remains of living organism that burried beneath the earth crust million of years ago.
Coal is non renewable because if once it gets depleted it will take a very very long time to replenish.

Find the force on an object which has a mass of 20 kg and an acceleration of 10 m/s2.
Answer:
200N
Explanation:
mass = 20 kg
acceleration = 10 m/s^2
Force = mass * acceleration
= 20 *10
= 200 N
What equations would you use to find force?
Answer:
F = m x a
Explanation:
F = force
m = mass of an object
a = acceleration

Substance A has twice the specific heat capacity as substance B. If 1000 J of heat are added to 1.0 kg of each substance, compare the change in temperature of each substance.
The specific heat capacity of copper is 390 J/Kg AC. What does this
mean?
Answer:
It means that 400 J of heat is the required amount to raise or lower thh temperature of a 1kg piece of copper
Explanation:
390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C
From the given information,
The specific heat capacity of copper is 390 J/Kg °C. To determine what this means, we will define the term specific heat capacity.
The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.
Therefore, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.
Hence, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.
