The moon has less gravity so the weight will change. The moon also has no air so the balloon will expand which changes its volume and density.

The only property unchanged is a. mass.

If all of the forces acting on an object are balanced, then:
kondaur [170]

A. the direction the object is moving in will not change.

B. the acceleration of the object will be 0 m/s2

Explanation:

We can answer this problem by using Newton's second law of motion:

\sum F = ma

where

\sum F is the net force acting on an object

m is the mass of the object

a is its acceleration

In this problem, all the forces acting on the object are balanced, therefore the net force is zero:

\sum F=0

which means that also the acceleration is zero:

a=0

Acceleration is equal to the rate of change of velocity: therefore, zero acceleration means that the velocity of the object does not change. We can now analyze the given statements:

A. the direction the object is moving in will not change.  --> TRUE, because the velocity is not changing.

B. the acceleration of the object will be 0 m/s2  --> TRUE, as we stated above

c. the object will not be in motion.  --> FALSE: we just know that its velocity is constant, but it can be different from zero

D. the velocity of the object will be 0 m/s. --> FALSE, for the same reason stated in C

What minimum speed does a 100 g puck need to make it to the top of a 4.60 m -long, 24.0 ∘ frictionless ramp?
mash [69]

Answer:

6.05 m/s

Explanation:

In order for the puck to reach the top of the ramp, its initial kinetic energy must be equal to its final potential energy.

So we can write:

KE=PE\\\frac{1}{2}mv^2 = mgh (1)

where

m = 100 g = 0.1 kg is the mass of the puck

v is the initial speed of the puck

g=9.8 m/s^2 is the acceleration due to gravity

h is the height of the ramp

Here we know that

d = 4.60 m is the length of the ramp

\theta=24.0^{\circ} is the angle of the ramp

So its height is

h=d sin \theta = (4.60)(sin 24.0^{\circ})=1.87 m

So now we can re-arrange eq (1) to find the minimum speed of the puck:

v=\sqrt{2gh}=\sqrt{2(9.8)(1.87)}=6.05 m/s

Who has the greater acceleration rate? A runner
Arturiano [62]
The first runner because it is very clear that accelarition depends on the time and we know that the time in this case is pretty simple
