An object has a fixed volume and a variable shape before it changes state.
After the change, it can change in both shape and volume. Which change of
state has occurred? (APEX)
A. Gas to liquid
B. Solid to liquid
C. Liquid to gas
D. Gas to plasma
Answers
Answer:
AExplanation:
The answer is C because the liquid has to turn into gas which the liquid has volume and a variable shape. Gas does not have volume or shape.
An object has a fixed volume and a variable shape before it changes state. After the change, it can change in both shape and volume then the change of state occurred was liquid to gas
What is the matter?
Anything which has mass and occupies spaces is known as matter ,mainly there are four states of matter solid liquid gases, and plasma.
These different states of matter have different characteristics according to which they vary their volume and shape.
Liquid has a fixed volume but it can change its shape to any form but gases can change their volume as well as shape, therefore the correct answer is C.

Todd and Angela set up a ramp and released several cars from the top. If Todd and Angela want to determine the average speed of their cars down the ramp, what information do they need? Group of answer choices
Answers
Answer:
The ramps length, height, degree, and the weight of the car.
Explanation:
Answer:
I think they need the slope of the ram(degree) .
& current gravitational acceleration
& the length of the ram and also l don't think mass of the cars are not needed becoz the acceleration of the cars are given by its,
Gravitational acceleration * sin( slope).
So then use that in v^2=u^2+2as equation.
s for length
a for acceleration
v for end velocity
u for start velocity

A car moving at 30 m/s has 900 kj of kinetic energy. What is the car’s mass?
Answers
900,000 = 450m
Mass = 2,000kg
If a car moving at 30 m / s has 900 kJ of kinetic energy, then the mass of the car would have been 2000 kilograms.
What is mechanical energy?Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.
As for the given problem, we have to find out the mass of the car if the car moving at 30 m/s has 900 kJ of kinetic energy.
Kinetic energy = 1 / 2 m v²
900000 = 0.5 × m × 30²
m = 1000 / 0.5
= 2000 kilograms
Thus, If a car moving at 30 m / s has 900 kJ of kinetic energy, then the mass of the car would have been 2000 kilograms.

A 25 N force is applied to a 1.4 kg mass on level ground. If a 5 N frictional force is present between the surface and the object, what is the magnitude of the acceleration of this object?
Answers
Given parameters:
Force applied to the mass = 25N
Mass of the body = 1.4kg
Frictional force = 5N
Unknown:
Acceleration of the object = ?
Solution:
The net force on the object;
Fapplied - Frictional force = net force (m x a)
m is the mass of the body
a is the acceleration
Input the parameters and solve;
25 - 5 = 1.4 x a
1.4a = 20
a = [tex]\frac{20}{1.4}[/tex] = 14.3m/s²
The magnitude of the acceleration of the object is 14.3m/s²

If the force acting on a cart doubles, what happens to the carts acceleration?
Answers
Answer:
If the force on a cart doubles, the acceleration of the cart doubles.
Explanation:
For this problem, we need to consider the following equation:
Force = Mass x Acceleration
We can reasonably assume that the cart will have constant mass in the given force system. With this assumption we can say the following relationship:
Force is directly proportional to Acceleration within the system.
Given that our force on the cart is doubled, then our acceleration of the cart must also be doubled. You can mathematically express this as follows:
F = MA
2F = M * 2A
Hence, if force doubles, the acceleration doubles.

b) What is the volume of sphere with absolute uncertainty? _____ +/ _____cm^3
Answers
Answer:
The percent uncertainty of the volume=[tex]\frac{15.70}{523.59} \times 100=2.99\%[/tex]
The volume of sphere with absolute uncertainty=[tex]523.59 \pm 15.7 cm^3[/tex]
Explanation:
Radius of sphere = 5 cm
Radius with uncertainty r'= [tex]5 \pm 0.05[/tex]
Volume of sphere = [tex]\frac{4}{3} \pi r^3=\frac{4}{3} \pi (r')^3[/tex]
[tex]V=\frac{4}{3} \pi (r')^3\\\frac{dV}{dr'}=4\pi (r')^2[/tex]
Where dV is the uncertainty in volume
dr' is the uncertainty in radius
[tex]dV=4\pi (r')^2 dr'\\dV=4 \pi (5)^2(0.05)\\dV=15.70\\V=\frac{4}{3} \pi (r')^3=\frac{4}{3} \pi (5)^3=523.59[/tex]
The percent uncertainty of the volume=[tex]\frac{15.70}{523.59} \times 100=2.99\%[/tex]
The volume of sphere with absolute uncertainty=[tex]523.59 \pm 15.7 cm^3[/tex]

Deposition
Explanation:
I took the quiz
Deposition is accompanied by a loss in energy as the particles become less energetic hence the entry involving deposition is wrong.
What is phase change?The term phase change simply means a change from one state of matter to another. Phase changes are often accompanied by a loss or gain in energy depending on what process occurred.
