Given :
Mass of block = 3.5 kgWeight of Block = 3.5 kgfVolume of water displaced when body is fully immersed = 1000 cm³Answer:
For calculating Upthrust on block we will have to first find out Volume of block :
↪Volume of block = Volume of water displaced
↪ Volume of block = 1000 cm³ = 0.001 m³
________________Now, we will calculate the Upthrust on block:
↪ Upthrust on block = Volume of block * Density of water * g
↪ Upthrust on block = 0.001 * 1000 * g
↪ Upthrust on block = 1 kgf

Brian made this table to organize his notes on changes of state.
A 2-column table with 4 rows. The first column titled change of state has entries melting, freezing, deposition, condensation. The second column labeled energy change has entries gain, lose, gain, lose.
Which change of state has the wrong energy change listed?
condensation
deposition
melting
freezing
Answer:
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.
The phase change deposition is accompanied by a loss in energy as the particles become less energetic hence the entry involving deposition is wrong.

How are extrusive rocks formed?
A. Magma gets trapped inside Earth and cools to rock.
B. Volcanoes apply force to solid rocks and eject them
C. Magma gets forced to Earth’s surface and cools to rock.
D. Volcanoes trap lava inside Earth, where it cools to rock.
Answer:
A
Explanation:
Answer: C
Explanation: Because if magma wasn't to be forced on earth's surface, the magma would come on earth and burn earth down.

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?
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

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
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

2. A sphere has a radius of 5.00 cm. with an uncertainty of 5%,
a) what is the percent uncertainty of the volume? _______%
b) What is the volume of sphere with absolute uncertainty? _____ +/ _____cm^3
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]
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
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.

If the force acting on a cart doubles, what happens to the carts acceleration?
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.
