1:12:11 Here's how to calculate the maximum height reached by the ball using the law of conservation of energy: 1. Initial Kinetic Energy: The ball is thrown upward with an initial velocity, so it possesses kinetic energy. The formula for kinetic energy is: Kinetic Energy (KE) = 0.5 * mass * velocity^2 Substituting the given values: KE = 0.5 * 10 kg * (15 m/s)^2 = 1125 Joules 2. Potential Energy at Maximum Height: At the maximum height, the ball's velocity becomes zero, meaning its kinetic energy is converted entirely into potential energy. The formula for potential energy is: Potential Energy (PE) = mass * gravity * height 3. Equating Kinetic and Potential Energy: According to the law of conservation of energy, the initial kinetic energy equals the potential energy at the maximum height: KE = PE Substituting the values: 1125 Joules = 10 kg * 9.81 m/s^2 * height 4. Solving for Height: Rearranging the equation to solve for height: height = 1125 Joules / (10 kg * 9.81 m/s^2) ≈ 11.47 meters Therefore, the maximum height reached by the ball is approximately 11.47 meters.
1:12:32 full explanation of answer is: Mass= 10 kg initial velocity= 15m/s final velocity=0(as when object is thrown vertically upwards the final velocity is considered 0) so at height 0 in bottom, the total energy acting in the ball would be kinetic, as the height is 0 and for potential energy you need some height so Total Energy= Kinetic Energy at bottom 1/2mv^2 1/2x10x15x15 1/2x10x225 1125 J so at heighest height for a fraction of time the object has 0 velocity which means it has potential energy at the top. so total energy at top = Potential energy 1125 = mgh 1125=10x10xh 1125/100= h 11.25m In this answer i have considered acceleration due to gravity to be 10, you can try with 9.8 also. edit: You can simply use the third equation of motion to understand but I tried to explain it conceptually.

SIR PLS TRY THIS Dark circles under the eyes can be treated with home remedies, lifestyle changes, and medical treatments: Home remedies Apply something cold to the under-eye area, such as a cold spoon, frozen peas, or a bag of tea bags. You can also try massaging your eyes with pure cow ghee or applying a combination of cucumber juice and rose water. Lifestyle changes Get enough sleep, elevate your head with pillows, and reduce stress. You can also try eating a well-balanced diet, avoiding too much alcohol, and stopping smoking. Medical treatments A healthcare provider can recommend treatment options, such as fillers or laser treatments. Most treatments are safe, but some may cause minor side effects like redness or swelling. Other things you can try include: Using products made to treat dark circles Using sunscreen with an SPF of at least 30 Taking antihistamines if allergies are the cause Minimizing sun exposure Using makeup concealer to cover the dark circles Drinking more water to stay hydrated

Here's how to calculate the maximum height reached by the ball using the law of conservation of energy:
1. Initial Kinetic Energy:
The ball is thrown upward with an initial velocity, so it possesses kinetic energy. The formula for kinetic energy is:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
Substituting the given values:
KE = 0.5 * 10 kg * (15 m/s)^2
= 1125 Joules
2. Potential Energy at Maximum Height:
At the maximum height, the ball's velocity becomes zero, meaning its kinetic energy is converted entirely into potential energy. The formula for potential energy is:
Potential Energy (PE) = mass * gravity * height
3. Equating Kinetic and Potential Energy:
According to the law of conservation of energy, the initial kinetic energy equals the potential energy at the maximum height:
KE = PE
Substituting the values:
1125 Joules = 10 kg * 9.81 m/s^2 * height
4. Solving for Height:
Rearranging the equation to solve for height:
height = 1125 Joules / (10 kg * 9.81 m/s^2)
≈ 11.47 meters
Therefore, the maximum height reached by the ball is approximately 11.47 meters.

1:12:32 full explanation of answer is:
Mass= 10 kg
initial velocity= 15m/s
final velocity=0(as when object is thrown vertically upwards the final velocity is considered 0)
so at height 0 in bottom, the total energy acting in the ball would be kinetic, as the height is 0 and for potential energy you need some height
so
Total Energy= Kinetic Energy at bottom
1/2mv^2
1/2x10x15x15
1/2x10x225
1125 J
so at heighest height for a fraction of time the object has 0 velocity which means it has potential energy at the top.
so total energy at top = Potential energy
1125 = mgh
1125=10x10xh
1125/100= h
11.25m
In this answer i have considered acceleration due to gravity to be 10, you can try with 9.8 also.
edit: You can simply use the third equation of motion to understand but I tried to explain it conceptually.
Thanks for reading
Height would be 11.48 m if g= 9.8
No, Gravity is taken as round off and it will be 10 only not 9.8....Actually it is correct in both ways
Ok
just use v^2-u^2=2as

225/20=h
11.25=h
therefore the max height is 11.25m
Check
v^2-u^2=2as
-u^2=-2gh
-225=-20h
225/20=h
h=11.25 m
Correct 💯
No .. gravitaional force not always act opposite

SIR PLS TRY THIS
Dark circles under the eyes can be treated with home remedies, lifestyle changes, and medical treatments:
Home remedies
Apply something cold to the under-eye area, such as a cold spoon, frozen peas, or a bag of tea bags. You can also try massaging your eyes with pure cow ghee or applying a combination of cucumber juice and rose water.
Lifestyle changes
Get enough sleep, elevate your head with pillows, and reduce stress. You can also try eating a well-balanced diet, avoiding too much alcohol, and stopping smoking.
Medical treatments
A healthcare provider can recommend treatment options, such as fillers or laser treatments. Most treatments are safe, but some may cause minor side effects like redness or swelling.
Other things you can try include:
Using products made to treat dark circles
Using sunscreen with an SPF of at least 30
Taking antihistamines if allergies are the cause
Minimizing sun exposure
Using makeup concealer to cover the dark circles
Drinking more water to stay hydrated
maybe bhiya dont drink or some to muchh or dont do
