Answer:
Is it 11.8m high or 0.6?
The question is not clear
When block is pushed upwards along the inclined plane
the net force applied on the block will be given as

here we know that
m = 75 kg


now plug in all values into this


now for finding the power is given as



Answer:
-5.29 m/s
Explanation:
Given:
y₀ = 1.43 m
y = 0 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: v
v² = v₀² + 2a (y − y₀)
v² = (0 m/s)² + 2(-9.8 m/s²) (0 m − 1.43 m)
v = -5.29 m/s
Answer:
1) 16.88 atm
2) 34.47 atm
Explanation:
Data:
Volume=0.700L
Temperature = 300K
Number of moles=0.480 mol
Ideal gas constant=0.082057 L*atm/K·mol
1) The ideal gas law is:
(1)
with P the pressure, T the temperature, n the number of moles, V the volume and R the ideal gas constant , so solvig (1) for P:


2) The vander Walls equation is:

solving for P
