Wind or gravitational pull. A wave is made by friction between wind and the water’s surface. Waves can also be made by the sun and moon’s gravitational pull on the earth.
<u>The number of variations the dealership have is 40 cars</u>.
Data given;
- The number of different product = 4
- The number of transmission = 2 (standard or automatic)
- The numbers of colors available = 5
<h3>Dealership variation </h3>
This is the total numbers of cars available in the dealer shop at the moment.
To get that, we simply multiply the numbers of colors available, the number of transmission and the makes of car available.
This is equal to
From the above calculation, we can say that <u>the variations the dealership offers is 40</u>

How much gravitational potential energy does the block have
when it gets to the top of the ramp ?
(weight) x (height) = (15 N) x (0.2 m) = 3 Joules .
If there were no friction, you would only need to do 3 Joules of work
to lift the block from the bottom to the top.
But the question says you actually have to do 4 Joules of work
to get the job done.
Friction stole one of your Joules along the way.
Choice-4 is not the correct one.
Choice-1 is the correct one.
===========================
Notice that the mass of the block is NOT 15 kg , and you
don't have to worry about gravity to answer this question.
The formula for potential energy is (m)·(g)·(h) .
But (m·g) is just the WEIGHT, and the formula
is actually (weight)·(height).
The question GIVES us the weight of the block . . . 15 N .
So the potential energy at the top is just (15N)·(0.2m) = 3 Joules.
Answer:
t= 2 sec
Explanation:
Given that
Ui= 16 m/s
Vi= 20 m/s
As we know that at the maximum height ,the y component of velocity will become zero.
We know that horizontal component of velocity will remain constant trough out the motion.
We also know that acceleration due to gravity is in downward direction.
Vf= Vi- g t
Now by putting the values
0 = 20 - 10 x t ( take g= 10 m/s²)
20 = 10 t
t= 2 sec
Therefore the answer is 2 sec.
