Thermal energy can be transferred in a few ways but friction is a good example, other ways include, radiation, convection, or conduction.
Actually Welcome to the Concept of the Projectile Motion.
Since, here given that, vertical velocity= 50m/s
we know that u*sin(theta) = vertical velocity
so the time taken to reach the maximum height or the time of Ascent is equal to
T = Usin(theta) ÷ g, here g = 9.8 m/s^2
so we get as,
T = 50/9.8
T = 5.10 seconds
thus the time taken to reach max height is 5.10 seconds.
Answer:
Initial temperature of the ideal gas is 447.4 K.
Explanation:
It is given that,
Initial volume, V₁ = 2.7 L
Final volume, V₂ = 1.75 L
Final temperature, T₂ = 17 °C = 290 K
We need to find the initial temperature of the gas. It can be calculated using Charles' law as :
So, the initial temperature of the ideal gas in a sealed container is 447.4 K. Hence, this is the required solution.
Answer:
28,400 N
Explanation:
Let's start by calculating the pressure that acts on the upper surface of the hatch. It is given by the sum of the atmospheric pressure and the pressure due to the columb of water, which is given by Stevin's law:
On the lower part of the hatch, there is a pressure equal to
So, the net pressure acting on the hatch is
which acts from above.
The area of the hatch is given by:
So, the force needed to open the hatch from the inside is equal to the pressure multiplied by the area of the hatch:
The wall exerts a force of equal magnitude but in the opposite direction. So the force by the wall is 10 N to the right.
