Answer:
to get it u have to multiple 6=00 time 89 to get the number 21 than plus it by 22 what is 31
Answer:
a) 6.26 m/s
b) 7.67 m/s
Explanation:
The potential energy at height h0 is initially ...
PE0 = mgh0
At height h1, the potential energy is ...
PE1 = mgh1
The difference in potential energy is converted to kinetic energy:
PE0 -PE1 = KE1 = (1/2)m(v1)^2
Solving for v1, we have ...
mg(h0 -h1) = (1/2)m(v1)^2
2g(h0 -h1) = (v1)^2
v1 = √(2g(h0 -h1))
__
a) When the body is 1 m high, its speed is ...
v = √(2(9.8)(3 -1)) ≈ 6.26 m/s . . . at 1 m high
__
b) When the body is 0 m high, its speed is ...
v = √(2(9.8)(3 -0)) ≈ 7.67 m/s . . . when it reaches the ground
Answer:
E = hf or 
Explanation:
The expression that gives the amount of light energy that is converted to other forms between the fluorescence excitation and emission events is given by :
E = hf
f is the frequency
c is the speed of light
is the wavelength
Hence, this is the required solution.

<h3>Introduction</h3>
Hi ! I will help you to explain about gravity. Gravity is one part of the force that will pull two or more objects that interact with each other to the center of their weight. Because it is a force, and interacts with mass, the gravitational force can also cause an acceleration called gravitational acceleration.The characteristic of gravity are:
- Mass cannot be affected by gravitational acceleration, because mass itself has formed gravitational interactions.
- The weight of an object is something that can be affected by the acceleration of gravity, because weight is a derived quantity in Newtons (N)
- The lighter object will fall to the heavier object because the center of mass will be closer to the object with greater mass.
<h2>Explanation</h2>
Let's go into more detail about my answer!
<h3>Moon's Orbit</h3>
The moon undergoes two motions, orbiting the Earth and orbiting the sun together. So, here the gravitational force from the Earth can be said to have more effect on the Moon. Without the influence of Earth's gravity, the moon will orbit the sun itself by the interaction of its own gravitational force with the sun.
<h3>Tides on Earth</h3>
The tides are caused by the Moon's gravitational force. Remember ! The Earth's gravitational force always points downwards to make a constant (so that water does not spill when it is hit by the Moon's gravity). The Moon's gravitational force also depends on how close it is to Earth.
<h3>Earth's Orbit</h3>
Like the Moon, the Earth orbits the sun. However, the sun is now creating a gravitational field. Not only for Earth, but for all objects in the solar system.

Answer:
Force on the singly charged ion will be 
Explanation:
We have given electric field E = 8 MN/C
So electric field in N/C will be 
It is given that ion so charge on ion will be equal to 
We have to find the electric force on the ion
Electric force is equal to 
, here q is charge and E is electric field
So force on the charge will be equal to 
So force on the singly charged ion will be
