B because why not i was wondering how ppl are so smart and let me tell ya i don’t know
A chemical reaction involves one or more reactants changing into new products
Answer:
0.733J/g°C
Explanation:
Using the formula
Q=mcΔθ
Q=38.5J, c=? , m=17.5g , Δθ=3°C
c= Q/(mΔθ)
c=0.733J/g°C
The correct order of events for the electromagnetic generators generate electricity is
b) The conducting coil rotates
c) The number of magnetic field lines passing through the coil changes
d) The flow of cuurent through the circuit
a)The stationary electrons in the wire experience a force.
The electromagnetic generators is working on the principle of electromagnetic induction. It has been used in many places as standby power sources in shops, homes etc.
It works by converting the mechanical energy into electrical energy by making use of electromagnetic conduction. which means the creation of current my moving the wire which is next to the magnet.

Answer:
754.6 m
Explanation:
The GPE (Gravitational potential energy) of an object with respect to the ground is given by
where
m is the mass of the object
g = 9.8 m/s^2 is the acceleration due to gravity
h is the heigth above the ground
Here we have
m = 12,400.05 kg is the mass
GPE = 91,700,000.00J is the GPE
Solving the formula for h, we find the heigth:
