Answer:
1217.6 kg m^{2} / s
Explanation:
mass (m) = 2 kg
length (L) = 4.6 m
angle = 1.0472 rad = 60 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
time (t) = 27 s
angular momentum = m x g x L x t x cosθ
angular momentum = 2 x 9.8 x 4.6 x 27 x cos 60 = 1217.6 kg m^{2} / s
To solve this problem it is necessary to apply Newton's first law which warns that every body remains in continuous motion or at rest until an external force acts on it.
From the statement it is said that there is no friction on the crate, then the sum of forces in the horizontal direction will be zero. Here as the truck is slowing down, there is not net horizontal force on the crate, it means that the crate is at rest.
The correct answer is e. No direction. The net force is zero.
When the system reaches 60° North latitude after moving away from the equator and passing directly over water, it will be at a point where most of its energy is lost.
The low pressure system will dissipate its energy as it propagates through the air and more energy will be lost due to the high content of water vapor in the air above the water.
Divide the change in speed by the time for the change.
Answer:
If we increase the temperature in a reactor by 54 degrees Fahrenheit [54°F], the temperature will increase by 12.22 degrees Celsius [12.22 ⁰C]
Explanation:
To determine the number of degrees Celsius the temperature will be increased, we convert from Fahrenheit to Celsius.
Converting from Fahrenheit to degree Celsius
54°F -----> °C
54 = 1.8°C + 32
54-32 = 1.8°C
22 = 1.8°C
°C = 22/1.8
= 12.22 °C
Thus, 54°F -----> 12.22 °C
Therefore, If we increase the temperature in a reactor by 54degrees Fahrenheit [54°F], the temperature will increase by 12.22 degrees Celsius [12.22 ⁰C]
