Answer:
324.76J
Explanation:
Given parameters:
Force of pull on the box = 25N
Displacement = 15m
Angle of pull = 30°
Unknown:
Work done by the force = ?
Solution:
Work done is the force applied on a body to move it through a particular distance.
It can be expressed as;
Work done = F x dcosФ
F is the force
d is the displacement
Ф is the angle
So;
Work done = 25 x 15cos 30 = 324.76J
Answer:
This is the answer bro hope it will help you
Answer:
457.8394 K
Explanation:
= Escape velocity = 2.38 km/s
T = Temperature
R = Gas constant = 8.314 J/mol K
M = Molar mass = 2.016 g/mol
The rms velocity of a molecule is given by
Here,
The temperature of the hydrogen molecule would be 457.8394 K
Our eyes detect light only within a range of frequencies called visible light.
