Answer:
1st Law- SO I try to push a elephant and it doesn't move because it has a very large mass.
2nd Laws-So after I try to push the elephant and then it kicks me back with a lot of force.
3rd Law- Now since I got kicked my legs broke and now my legs have to be rehiblitized and coaches put me in a team and I push against the wall and swim and that would be an action reaction.

Where = 0.0279 m³, = 280 K and = 320 K
=>
=> = 0.03189 m³
Answer:
An electric generator creates a time-dependent induced voltage.
An electric generator converts mechanical energy into electrical energy.
Explanation:
An electric generator works on the principle of electromagnetic induction. This phenomenon hinges on the fact that moving a conducting wire through a magnetic field produces electricity. Electricity is generated as long as there is relative motion between the conductor and the magnetic field. The emf generated is known as induced emf or induced voltage.
The electric generator converts mechanical energy to electrical energy.
Answer:
Length = 2.453 m
Explanation:
Given:
Resistivity of the wire (ρ) = 1 × 10⁻⁶ Ω-m
Diameter of the wire (d) = 0.250 mm = 0.250 × 10⁻³ m
Resistance of the wire (R) = 50 Ω
Length of the wire (L) = ?
The area of cross section is given as:
We know that, for a constant temperature, the resistance of a wire is directly proportional to its length and inversely proportional to its area of cross section. The constant of proportionality is called the resistivity of the wire. Therefore,
Expressing the above in terms of length 'L', we get:
Plug in the given values and solve for 'L'. This gives,
Therefore, length of No. 30 wire (of diameter 0.250 mm) is 2.453 m.
Acceleration is measured in meters per second square.
