PLZZZ HELP
Doss [256]

Answer/Explanation:

The weight of an object is defined as the force that is exerted due to the gravitational force.

Mathematically, it can be written as :

W = m g

Where

m is the mass of the object

g is the acceleration due to gravity

Also,  

We know that the value of g varies with respect to the location. At the equator, the value of g is less as compared to the poles.

The feature of an object that affects its weight are :

Mass of the object

Location of the object

How much force Earth exerts on the object

if an object 18mm high is placed 12mm from a diverging lens and the image is formed 4mm in front of the lens what is the height
brilliants [131]

To solve this problem we use an amplification formula for divergent lenses

M = \frac{i}{o} = \frac{h'}{h}

Where:

i: distance of the image to the lens

o: Distance from the object to the lens

h = height of the object

h '= height of the image

M = \frac{4mm}{12mm} = \frac{h'}{18mm}

h'= 18mm\frac{4mm}{12mm}

h '= 6 mm

The height is 6 mm

A grasshopper jumps at a 65.0 degree angle at 5.42m/s. At what time does it reach its maximum height?
crimeas [40]
When the grasshoppers vertical velocity is exactly zero.
v = -g•t + v0.
v: vertical part of velocity. Is zero at maximum height.
g: 9.81
t: time you are looking for
v0: initial vertical velocity
Find the vertical part of the initial velocity, by using the angle at which the grasshopper jumps.
