Answer:
776.6 w
1.04 hp
Explanation:
given:
Mass, m = 190kg
height change, h = 25m
time elapsed, t = 60 s
acceleration due to gravity, g = 9.81 m/s²
Potential energy required raising 190 kg of water to a height of 25m
= mgh
= 190 x 9.81 x 25
= 46,597.5 J
Power required in 60 s
= Energy required ÷ time elapsed
= 46,597.5 ÷ 60
= 776.6 Watts (Use conversion 1 W = 0.00134102 hp)
= 776.6 w x 0.00134102 hp/w
= 1.04 hp
Answer:
The objects morion will remain the same
Explanation:
Who pays the income tax, the payroll tax, the estate and gift taxes? Who
bears the burden of the gasoline and tobacco taxes? If Congress were to
raise this tax rate, or lower that tax deduction, who would gain and
who would lose? The outcomes of the political battles over changes in
the tax system often hinge on the answers to such questions. This paper
will discuss the economic consequences of taxation and the factors that
influence where the burden of various taxes really falls. It will review
some of the discussions in the economic literature. Finally, it will
suggest that a shift to a markedly different type of tax system would
benefit all players in the economy.
Answer:
10m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity = 100m/s
Time taken = 10s
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time.
A = 
v = final velocity
u = initial velocity
t = time taken
So, insert the parameters and solve;
A = 
= 10m/s²
