Answer:
A)Temperature at which liquid starts to become gas.
Explanation:
Boiling point is the temperature at which a liquid boils and turns to vapour or gas.
From the law's of physics, we can know about the different boiling points for different liquids. As an example: at 100 °C temperature the water starts to change into the vapor. It's the boiling point of the water.
Answer:
Acceleration:
Final velocity:
Explanation:
To calculate the acceleration, you start from the formula:
Thus:
Now that you have the accelration, you can use the this formula to calculate the final speed:
Thus:
Answer:
The total momentum of the cat and the dog is, p = 2.4 kg m/s
Explanation:
Given,
The mass of the cat, m = 800 g
= 0.800 kg
The mass of the dog, M = 1000 g
= 1 kg
The velocity of the cat taken positive x direction, v = 8 m/s
The velocity of the dog, V = - 4 m/s
The momentum of the body is defined as the product of its mass and velocity.
p = mv
The momentum of the cat,
p₁ = 0.8 x 8
= 6.4 kg m/s
The momentum of the dog,
p₂ = MV
= 1 x -4
= -4 kg m/s
The total momentum,
p = p₁ + p₂
= 6.4 + (-4)
= 2.4 kg m/s
Hence, the total momentum of the cat and the dog is, p = 2.4 kg m/s
The number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.
<h3>
Average daily power consumption</h3>
The average daily power consumption is the amount of electric energy consumed by an individual on a daily rate.
The average daily power consumption of individuals in USA is 12,100 W-hr.
<h3>Converting watts to kilowatts</h3>
E = 12,100 Whr/1000
E = 12.1 kWh
Thus, the number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.
