Answer:
Hope this helps!! :D
Explanation:
Mechanical energy is power that an object gets from its position and motion. the energy released during nuclear fission or fusion, typically to make electricity.
Thermal energy is the energy given off by hot things like fire.
Chemical energy is energy stored in the bonds of chemical compounds.
Electromagnetic energy is a form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel.
Electrical energy is energy derived from electric potential energy or kinetic energy.
Nuclear energy is the energy released during nuclear fission or fusion, typically used to generate electricity.
Answer: B
Explanation: The motion sensor will measure the speed (velocity) of the car. Since the mass of the car has been measured, we can use formulas to calculate the average force.
Average net force = mass × acceleration
The mass of the toy car is measured first and noted
To calculate the velocity,
the car starts from rest since the velocity is associated with the distance and time after 5s.
Acceleration = velocity/time
With that the acceleration can be found.
acceleration is defined as change in velocity per unit time.
Then,
Force = mass × acceleration
Option B is the best answer
Answer: 0.8 nC
Explanation: In order to explain this problem we have top use the expression for the capacitor of parallel plates, which is given by:
C=εo*A/d where A and d are the area and the separation of the plates.
Then we have
V=Q/C so ΔV= Q* Δd/(εo*A)
Q= 100* 0.054*8.85*10^-12/( 0.06)=0.8 nC
Answer:
Explanation:
As we know that in AC circuit we have
here we have
V = 59 V
i = 5.05 A
so we will have
also we know that
here we will have
As per kinematics equation we are given that
now we are given that
a = 2.55 m/s^2
now we need to find x
from above equation we have
so it will cover a distance of 93.2 m
