The wavelength is equal to Planck's constant divided by the ball's momentum.
This means that:
lambda = h / p .............> equation I
Momentum = mass * velocity ............> equation II
Substitute by equation II in equation I, you get:
lambda = h / mv
Now, we are given:
lambda = 8.92 * 10^-34 m
Planck's constant = 6.625 * 10^-34
velocity = 40 m/sec
Substitute with these givens in the above equation to calculate the mass as follows:
8.92*10^-34 = (6.625*10^-34) / (40*m)
mass = 0.0185678 kg
Answer:
Both technicians are correct
Explanation:
Insulated rubber gloves or lineman’s gloves are a major requirement to ensure safety when working with high voltage parts of the hybrid electric vehicles because rubber is an insulator i.e. it does not allow direct contact of electricity with the body. These gloves are really important because these gloves can protect the technicians from electric shocks servicing the high voltage system on hybrid electric vehicles. It needs to be ensured that the gloves are of pure rubber and have no holes or cuts to ensure complete insulation. These gloves are also called class “0” gloves or gloves rated at 1000 V are used for this.
Similarly there are methods to shut off the high voltage to components and circuits in hybrid cars. These methods include but are not limited to:
• Turning the ignition off
• Disconnecting the 12-volt auxiliary battery
• Removing the main fuse, relay, or HV plug
So both the technicians are correct
Measure the distance between an object and the lens after using the lens to focus on it. The focal length is at this range.
<h3>How simple is it to determine a lens's focal length?</h3>
Focus a far-off object on a wall by adjusting the convex lens up and down along the scale. The picture that forms on the wall is very close to the lens' focus, and the metre scale can be used to read how far away the lens is from the image. This approximates the lens's focal length.
<h3>How do you calculate a concave lens's focal length?</h3>
The formula f=uv/u-v is used to get the focal length of the concave lens using the values of u and v.

Answer:
Acceleration,
Explanation:
It is given that,
Mass of Gary, m = 80.5 kg
Mass of his bicycle, m' = 13.7 kg
Net unbalanced force acting on him, F = 9.86 N
Let a is the value of acceleration. Both cycle and Gary will move with same acceleration. Using the second law of motion to find it as :
or
So, the value of acceleration of the Gary and bicycle is . Hence, this is the required solution.
no:
because your hair is a mixture of your dad and mom and their dads and moms
its not like you only get your moms genes or only your dads genes
so its a mixture
hope i helped
