SOLUTION:
Total amount of fruit = Total amount of apples + Total amount of pears + Total amount of oranges
Total amount of fruit = 15 / 4 + 29 / 4 + 81 / 8
Total amount of fruit = 30 / 8 + 58 / 8 + 81 / 8
Total amount of fruit = 169 / 8
Total amount of fruit = 21.125 kg
ANSWER:
Therefore, the chief bought 21.125 kg of fruit all together.

Answer:
when all else remains the same, what effect would decreasing the focal have known a convex lens
Explanation:
It would cause the lens to produce only real images
( Hope This Will Help U Out!!)
Answer:
0.00288 J
Explanation:
We know that
W= Fds
F = −α∆s^4
α = 45 N/m^4 and ∆s = displacement
W= −α∆s^4ds
integrating both the sides from s= 0 to 0.2
W= 45/5×0.2^5= 0.00288 J
The statement which describes how a machine can help make work easier is that It can put out more force than the input force by decreasing the distance over which force is applied, therefore the correct option is option A.
<h3>What is work done?</h3>
The total amount of energy transferred when a force is applied to move an object through some distance
The work done is the multiplication of applied force with displacement.
Work Done = Force * Displacement
As work done depends both on the force as well as the displacement force and be reduced by reducing the displacement if the same amount of work is performed by the machine.
The correct answer is option A since the statement that describes how a machine might assist in making work easier says that it can put out greater force than the input force by reducing the distance over which force is exerted.

The horizontal speed has no effect on how long it takes to reach the ground.
A bullet shot from a gun and a bullet dropped from the front end of the gun
at the same time as the shot both hit the ground at the same time.
The number that counts is the height from which it fell . . . the 1.25 m.
I'll use this very useful formula:
Distance of free fall,
starting from rest = (1/2) · (gravity) · (time)²
1.25 m = (1/2) · (9.8 m/s²) · (time)²
Divide each side
by 4.9 m/s² : 1.25 m / 4.9 m/s² = time²
0.2551 sec² = time²
Square root each side: 0.505 sec = time
It looks like the correct choice is approximately 'A'. (rounded)
