Answer:
W = 0J
Explanation:
The work done by the dresser is described as
W = f d (cos θ)
F has been given as the weight of this dresser. And it is 3500 N
d = 0 m
When you put these values into the equation
W = 3500 x 0 x cosθ
W = 0 J
This value tells us that the work done on this dresser is zero. No work has been done. Therefore the last option answers the question.
150(x+5)-150x=x(x+5)
150x+750-150x=x^2+5x
x^2+5x-750=0
(x-25)(x+30)=0
x=25
Answer:
False
Explanation:
The depending on what type of pressure is enclosed in a object, the smaller the object the more pressure because that pressure has limited room to escape.
Answer:
Explanation:
The acceleration of an object is the rate of change of velocity. The mathematical expression for the acceleration of an object is given by :
Where
v and u are final and initial velocities
t is time
or we can write acceleration as :
Hence, this is the required solution.
Answer:
3 hours 71 minutes
Explanation:
As because Speed= distance/time taken
so time taken= 3.71
