Answer:
The answer to your question is: W = 2063.4 J
Explanation:
Data
Force = 157 N
angle = 25°
distance = 14.5 m
W = ?
Process
- Find the horizontal force
cos Ф = adjacent side / hypotenuse
adjacent side = hypotenuse x cosФ
a.s. = 157 x cos 25
a. s. = 142.3 N
- Find the work
W = F x d
W = 142.3 x 14.5
W = 2063.4 J

Answer:
Newton's third law of motion.
Explanation:
An ice skater at rest pushes against a sled at rest,causing both the skater and sled to move away from each other with different acceleration. It is based on Newton's third law of motion.
Third law says that, for every action there is an equal; and opposite reaction. Here, action is force applied by ice skater and reaction is motion of skater and sled away from each other with different acceleration.

Answer:
Temperature of neon gas = 875 K
Explanation:
Using Ideal gas equation as:
PV=nRT
Where,
P is the pressure of the gas
V is the volume of the gas
n is the number of moles
R is the gas constant
T is the temperature
Also,
The ideal gas equation can be written as:
Thus,
As Density and Pressure is constant , We only consider molar mass and Temperature which are directly proportional according to the equation above as:
Data given for He:
Temperature (T₁) = 175 K
Molar mass of He (M₁)= 4 g/mol
For Ne:
Temperature (T₂)= ?
Molar mass of He (M₂)= 20 g/mol
Applying in the equation,
<u>Temperature of neon gas = 875 K</u>
