Answer:
2000 W
Explanation:
First of all, we need to find the output voltage in the transformer, by using the transformer equation:
where here we have
V1 = 200 V is the voltage in the primary coil
V2 is the voltage in the secondary coil
N1 = 250 is the number of turns in the primary coil
N2 = 500 is the number of turns in the secondary coil
Solving for V2,
Now we can find the power output, which is given by
P = VI
where
V = 400 V is the output voltage
I = 5 A is the output current
Substituting,
P = (400 V)(5 A) = 2,000 W
Answer:
Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other. ... This occurs twice each month. The moon appears new (dark) when it is directly between the Earth and the sun. The moon appears full when the Earth is between the moon and the sun.
Answer: D) a stone lies on the ground
Explanation:
Potential energy this is defined as the mechanical energy, energy stored, or energy created by the position of an object. Example; energy possessed by a ball while hanging at the top of a steep hill when about to roll down is called a potential energy. This is same as a stone which lies in a floor.
Answer: 53 m
Explanation:
Work = Force × Displacement
W= F s cosΘ
Where, s is the displacement and F is the force. Θ is the angle between force and displacement
F cosθ is the component of force acting in the horizontal direction.
The air pump applies F = 150 N force at an angle Θ = 45°
W = 5600 J
⇒s = W/F cosθ
Thus, the horizontal distance the water bottle rocket travels is 53 m
