There are many types of machine what type well for every day machines like treadmills is sweating, dehydration, loss of calories or fat.
Answer:
300K, 600K
Explanation:
ΔS =nCp ㏑()
= (2.5) (78.314) ㏑() = 14.41
Qp =(2.5) (8.314) (T2-T1)
= 6236 J.
=> 20.8 (T2-T1) - 6236
=> T2-T1 = 300
=> T2=T1 + 300
20.8 ㏑() =
=>
=> T1 = 300K
=> T2 = 600K
Answer:
v = 10 m/s
Explanation:
Given,
Length of the vine, l = 36 m
Angle of inclination = 31.0◦ with the vertical
acceleration due to gravity = 9.81 m/s²
Using Conservation of energy
KE = PE
v = 10 m/s
Hence, the speed of the swing is equal to 10 m/s
Answer:
Explanation:
Given that,
An object starts from rest at the origin (x₀ = 0) and travels in a straight line with a constant acceleration (a = constant).
The relation between the position (x) and time (t) is given by :
Let v is the velocity of the object.
Let a is the acceleration of the object. It is given by :
So, the acceleration of the object is . Hence, this is the required solution.
Given that,
Bulk modulus
Change in volume
Edge
The volume of the cube at the ocean's surface will be
Where, a = edge
Put the value into the formula
We need to calculate the change in pressure
Using formula of pressure
Put the value into the formula
The pressure increases by for every meter of depth
We need to calculate the depth
Using formula for depth
Hence, The depth is 9.75 m.
