repal postive to postive or negitve to negtive
The power is equal to energy transferred per unit time.
So, here power will be due to potential energy of the water kept at a certain height. And water is flowing down at the given flow rate.
The flow rate of water is 200kg/s
And the height given is : 15m
So, we calculate the potential energy as: mgh
Where m is the mass,
g is acc due to gravity = 9.8m/s
h is the height
So, potential energy = 200kg*9.8*15
= 29,400 J
Therefore, the maximum power generated is 29400 J/sec = 29400 Watts
Answer:
20 A
Explanation:
Given
Spring pulled from position
x = 5A
we need to calculate total distance of one full cycle of spring motion
if you see image below, you understand easily
When cycle complete
Its total distance become 20 A
Answer:
repulsion force es R = 5,224 10⁻³ N
Explanation:
We use Newton's second law to add forces, the elective force is repulsive because the asteroids have the same type of charge and gravitational force is always attractive.
Gravitational force
Fg = G m1 m2 / r²
Fg = 6,673 10⁻¹¹ 5.7 10⁴ 5.5 10⁴/190²
Fg = 5,795 10⁻⁶ N
Electric force
Fe = k q1 q2 / r²
Fe = 8.99 10⁹ 14.0 10⁻⁶ 15.0 10⁻⁶ / 190²
Fe = 5.2296 10⁻³ N
The resulting force is
R = Fe - Fg
R = 5.2296 10⁻³ - 5.795 10⁻⁶= 5229.6 10⁻⁶ - 5,795 10⁻⁶
R = 5,224 10⁻³ N
this is a repulsive force and the asteroids move away from each other
