Answer:
= -1.984 Diopters
Explanation:
The lens should form an upright, virtual image at the far point.
Therefore;
The image distance, V will be -50.4 cm, since the image is virtual.
For objects at very far distant the object distance,u, will be ∞ ; This means that focal length, f, will be equivalent to image distance, v, that is -50.4 cm
Therefore; f = -50.4/100 = -0.504 m
But, since Power of a lens, P, is given by the reciprocal of focal length in meters, (1/f)
Then, power will be given by;
Power = 1/f
= 1/-0.504 m
=- 1.984
Power is measured in Diopters
Hence <u>= -1.984 Diopters</u>
If you include the effects of falling through air, then you have to know the
shape, size, weight, and surface texture of the objects. You also have to
know the height from which they're dropped, and the temperature, pressure,
and humidity of the air. All these things make a difference in how they fall.
If you ignore the effects of falling through air, like build a giant metal tank
and pump all the air out of it, and ONLY talk about the effects of gravity, then
ALL OBJECTS accelerate at the same rate. If you drop two things from the
same height at the same time, then they both hit the ground at the same time,
traveling at the same speed, no matter what they are. They could be a piece of
tissue and a car !
There are several museums where they have a big glass pipe that you can
see through, and they pump the air out of the pipe and drop a feather and a
bowling ball from the top inside at the same time, and they both reach the
bottom together.
If gravity is the only force on an object, then all objects fall at the same rate.
Answer:
The magnitude of the motorcycle's acceleration is 5.20 m/s².
Explanation:
Given that,
Mass of motorcycle = 296 kg
Angle = 26.2°
Force on motorcycle= 3106 N
Force = 286 N
We need to calculate the magnitude of the motorcycle's acceleration
The net force acting on the motorcycle
Using newton's second law
Put the value into the formula
Hence, The magnitude of the motorcycle's acceleration is 5.20 m/s².
