Answer:
900kJ
Explanation:
Work done hereis lifting that water mass on to the surface level
v = volume of the tank
d= density of water (1000kg/m3)
g = gravotational acceleration
workdone=Weight * distance
= (v*d*g)*distance
=
Answer:
Explanation:
The magnitude of the acceleration in the x direction is always zero: TRUE.
At the apex, in the y direction the velocity is zero and the accelration is positive. TRUE.
At the apex, in the x direction, the velocity is zero and the acceleration is zero. FALSE. The accelration is zero, but the velocity is the same it had when it was shot.
The magnitude of the velocity in the y direction is always constant. FALSE, it's subject to gravity and it's velocity varies as
At the apex, in the Y direction, the velocity is negative and the acceleration is zero. FALSE. Velocity is zero, Acceleration is , towards the negative y axis
Explanation:
The given data is as follows.
F =
q =
v = 385 m/s
= 0.876
Now, we will calculate the magnitude of magnetic field as follows.
B =
=
= T
= 10.65 T
Thus, we can conclude that magnitude of the magnetic field is 10.65 T.
