Answer:
Power rating on the blender = 3809.52 Watts
Explanation:
We have expression for power equal to ratio of work and time,
Energy used by blender = Work done by electricity = 0.8 MJ =
Time of using blender = 3.5 minutes = 210 seconds
So power of blender = 800000/210 = 3809.52 Watts
Power rating on the blender = 3809.52 Watts
Answer:
960 in^3
Explanation:
Given data
Length= 24in
Width= 10in
Height = 12in
The volume of the tank
V= L*W*H
Substitute
V= 24*10*12
V= 2880 in^3
The volume of the water in the tank is
V=24*10*8
V=1920 in^3
Hence the volume of water need to fill the tank is
=2880-1920
=960 in^3
Answer:
Explanation:
Given that,
Mass of the object, m = 29 kg
Torsion constant of the wire, K = 1.14 N-m
Number of cycles, n = 98
Time, t = 74 s
To find,
The rotational inertia of the object.
Solution,
Relationship between the moment of inertia, time period and the torsion constant of the spring is given by :
Where I is the moment of inertia
K is spring constant
Let T Is the time period of oscillation, such that,
So, the rotational inertia of the object is .
