Answer:
The change in potential energy of the mass as it goes up the incline is 0.343 joules.
Explanation:
We must remember in this case that change in the potential energy is entirely represented by the change in the gravitational potential energy. From Work-Energy Theorem and definition of work we get that:
Where:
- Gravitational potential energy, measured in Joules.
- Mass, measured in kilograms.
- Gravitational acceleration, measured in meters per square second.
- Change in vertical height, measured in meters.
This work is the energy needed to counteract effects of gravity at given vertical displacement.
If we know that 
, 
and 
, the change in the potential energy of the mass as it goes up the incline is:
The change in potential energy of the mass as it goes up the incline is 0.343 joules.
Answer:
bacteria
Explanation:
where do primary consumers get their nitrogen from? ... Bacteria alter the nitrogen into a form that plants are able to use. Other types of bacteria are able to change nitrogen dissolved in waterways into a form that allows it to return to the atmosphere.
Answer:
R = 5.20 Ω, L = 6.24 10⁻⁴ H
Explanation:
The current in an RL circuit is
I = 
τ = L / R
In the problem they indicate the value of the voltage, the current and the time constant, for which the resistance must be found
The stable current is when enough time has passed (t »τ) after closing the circuit, therefore the exponential term is very small and we can neglect it.
I = E / R
R = E / I
let's calculate
R = 13.0 / 2.50
R = 5.20 Ω
now with this value we can find the inductance of the coil
τ = L / R
L = τ R
L = 1.20 10⁻⁴ 5.2
L = 6.24 10⁻⁴ H
Answer:
Option(B),option(C) and Option(D) are the correct answer to the given question .
Explanation:
- In the option(B) if we apply the force to stop the car. The motion and force of car is in the opposite direction .Suppose the person is moving the car to the straight and person immediately apply break the back wheel of the car is stop this means that force and direction of motion is opposite that's why this is correct .
- In the option(C) the ball and batsman hinting the ball is in the opposite direction .Suppose the ball is coming to the batsman to the right and it hits to the left its a opposite direction Therefore in this the force and direction of motion is opposite that's why this is correct .
- In the option(D) if the person drawing water from a well there is always upward force is applied but there is always motion is there i.e downward force i,e mg.that's why force and direction of motion is opposite that's why this is correct .
- In the option(A) the force of opening the door of force and the motion is in the same direction therefore it is not the against the direction of motion that's why this option is incorrect .
