Answer:
32000cm^3
Explanation:
Length L be base length
h be the height
Volume=V
V=L^2h
Surface area if box= L^2+4lh=4800
Solving for h
(4800-l^2/4L)=h
1200L-L^3/4=h
Substitute for h in V =L^2h
v=1200L-L^3/4
Differenting =1200-3*L^2/4=0
L=√(1600)=40
Substitute L=40
In V=1200L-L^3/4
Hence 1200*40-40^4/4=32000cm^3
Answer:
C
Explanation:
C. Curved lines or straight lines
The force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity is known as weight.
Weight is the force of gravity acting on a body.
The formula is :
W =mg
Here,
W is the weight or force acting on the body. m is the mass of the body, and g is the gravitational acceleration.
Since weight is also a force, so its SI unit is also newton. The value of weight varies from place to place depending on the gravity. Its value can also be equal to zero.

Answer:
0.3257 seconds
39.67 m/s
Explanation:
Speed = 263 km/h
Converting to m/s
Distance to travel = 23.8 m
Time = Distance / Speed
The time taken to go from one end of the court to the other is 0.3257 seconds
Time = 0.6 s
Speed = Distance / Time
The speed of the tennis ball is 39.67 m/s
Answer:
The magnitude of magnetic field of both wires is β= 13. 33
T
Explanation:
Using the right hand rule field magnetic as the current go in opposite direction the field in the point exactly in the middle have the same direction both so
They have the same direction and the P point is the middle as the same current field can be find:
T
=13.33T
