Option B makes the most sense. Option A is something you acquire, it wouldn't really cost anything. Utilities usually do not cost more than housing. Savings are subjective, dependent on the person. So option B.
Hope it helps!
Answer:
Danny hits the water with kinetic energy of 5000 J.
Explanation:
Given that,
The Weight of Danny Diver,
F = 500 N
m*g= 500 N
He steps off a diving board 10 m above the water.
h=10 m
when Danny diver hits water he generates the kinetic energy.
We need to find the kinetic energy of the water.
Let kinetic energy is K.
K = m*g*h
Where g is acceleration due to gravity.
that g= 9.8 m/s^2
now substituting the values in above equation
K= (500) * 10
K= 5000 J
Hence,
he hits the water with kinetic energy of 5000 J.

Answer:
Real time operating system (RTOS)
Explanation:
- Real time operating system is an operating system software which is used for the real-time applications that processes the data as soon as the input comes to the system.
It is very fast because it processes the data without any buffer delays.
- In RTOS the scheduler provides a deterministic time which is predicted for the execution pattern. In a real-time operation the system must respond to each sequence of execution within a certain time frame which is the deadline for the operation so that the next inline process can be executed. Hence it is used in embedded systems and circuitry devices.
The momentum of truck is 20790 kg m/s
<em><u>Solution:</u></em>
Given that we have to find the momentum of truck
From given, 1155 kg truck has a velocity of 18 m/s
Therefore,
Mass = 1155 kg
Velocity = 18 m/s
<em><u>The momentum is given by formula:</u></em>
Where, m is mass in kg and v is velocity in m/s
Substituting the values we get,
Thus momentum of truck is 20790 kg m/s
Answer & Explanation:
Definition:
Mass informs us about how much matter is present in a body. It is the measure of the inertia of a body. It can be measured by measuring the force of gravity acting on it on earth.
On the other hand, Momentum is the quantity of motion of the body. It depends depends upon velocity and the direction of the motion of the body.
Unit:
The SI unit of mass is kilogram (kg) while the SI unit of momentum is kg.m.s-1.
Formula:
Mass = Momentum / Velocity
Momentum = Mass * Velocity
or p = mv
Type:
Mass is scalar quantity while Momentum is a vector quantity.
