Answer: A combination 0 degrees Celsius and 101.3 kPa or 1 atm correctly describes standard temperature and pressure.
Explanation:
The term standard temperature and pressure is also known as STP and it is most commonly used when we want to calculate the density of a gas.
The term standard temperature means Fahrenheit or
or 273 Kelvin. On the other hand, term standard pressure means 1 atmosheric pressure of a gas.
Thus, we can conclude that a combination 0 degrees Celsius and 101.3 kPa or 1 atm correctly describes standard temperature and pressure.
Answer:
Resultant force will be 123.57 N
Explanation:
We have given that force in north direction and force in east direction
which is clearly shown in bellow figure
We have to find the resultant force
Resultant force is given by
So the resultant force will be 123.527 N
For the swimmer to go straight the sin component of his velocity should cancel the river velocity.
So, we have θ
This angle θ is the angle shall the swimmer point upstream from the shore.
0.32 = 0.85 sin[/tex]θ
θ =
The velocity of swimmer across the river is given by cos componet of his velocity
v = 0.85 cosθ = 0.85 cos 22 = 0.79 m/s
Answer:
L= 30 kg.m²/s
Explanation:
Given that
m = 2 kg
v= 3 m/s along x direction
y= 5 m
As we know that
Linear momentum P
P = m v
The angular momentum is the moment of linear momentum.
So the angular momentum L
L = m v r
Here r= 5 m
By putting the values
L = m v r
L = 2 x 3 x 5 kg.m²/s
L= 30 kg.m²/s
