HELP!!! The planet Mars has a mass about one-tenth the mass of Earth. Even though Mars has two moons, their tidal forces have a

much weaker effect on Mars than Earth’s moon does on Earth. Why do you think this is? Use the data in the tables to support your prediction.

Answer:

Say: Mars has a much weaker gravity effect than it does because it is smaller and cannot have as much gravity effect than it does on earth.

NikAS [45]

Answer:

a=1.024m/s

t=15.62s

Explanation:

A body that moves with constant acceleration means that it moves in "a uniformly accelerated movement", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.

When performing a mathematical demonstration, it is found that the equations that define this movement are as follows.

Vf=Vo+a.t                         (1)

{Vf^{2}-Vo^2}/{2.a} =X      (2)

X=Xo+ VoT+0.5at^{2}      (3)

X=(Vf+Vo)T/2                   (4)

Where

Vf = final speed

Vo = Initial speed

T = time

A = acceleration

X = displacement

In conclusion to solve any problem related to a body that moves with constant acceleration we use the 4 above equations and use algebra to solve

for this problem

Vf=16m/s

Vo=0m/s, the cart starts from the rest

X=125m

we can use the ecuation number tow to calculate the acceleration

{Vf^{2}-Vo^2}/{2.a} =X

{Vf^{2}-Vo^2}/{2.x} =a

{16^{2}-0^2}/{2(125)} =a

a=1.024m/s

to calculate the time we can use the ecuation number 1

Vf=Vo+a.t    

t=(Vf-Vo)/a

t=(16-0)/1.024

t=15.62s

As shown in the diagram, two massless wires connect a rotating pole to a sphere of mass 7.2 kg. The sphere revolves in a horizon

Use Fnet=ma. Apply it to the vertical components of all the forces acting on the ball and since tension is the same on both wires you should be able to factor it out and solve for it. Picture below

Why is a protective apron or lab coat important to use when working with acids?
Oksanka [162]

Answer: Option (C) is the correct answer.

Explanation:

Whether an acid is weak or strong it will cause harm if it comes in direct contact with the skin, eyes or mouth etc.

Thus, in order to prevent oneself, it is advised to wear a lab coat while working in laboratory as acids break down fabrics and can cause burns if the acids are strong.

Hence, a lab coat acts as a protective layer on the clothes so that even if acid falls on it then it might not reach the skin immediately and on time prevention can be taken.
