Answer:
The energy that is changing during a phase change is potential energy. During a phase change, the heat added (PE increases) or released (PE decreases) will allow the molecules to move apart or come together. Heat absorbed causes the molecules to move farther apart by overcoming the intermolecular forces of attraction.
Answer: I believe it turns into kinetic energy
Step-by-step explanation:
Kinect energy is the opposite of potential energy
find the radius given the linear speed and rate of rotation v=24.8m/s, 120 rev/mins
Answer:
I got you Fam
Step-by-step explanation:
The radius is 12.4 meters if the linear speed and rate of rotation v=24.8m/s, 120 rev/mins.
What is angular acceleration?It is defined as the rate of change in angular velocity with respect to time. It is also known as rotational acceleration.
It is given that:
The rate of rotation v = 24.8 m/s
The angular velocity w = 120 rev/mins
In rev/second
The angular velocity w = (120/60) rev/second = 2 rev/sec
The formula:
v = rw
Here r is the radius
r = v/w
r = 24.8/2
r = 12.4 meters
Thus, the radius is 12.4 meters if the linear speed and rate of rotation v=24.8m/s, 120 rev/mins.

In the figure below, o ll m. Find the values of y and z
Answer: y = 117 and z = 32
Step-by-step explanation:
y: 180 - 63 = 117
z: 180 - 117 (also known as y) = 63 which is the top corner right next to the equation for z, so you do it again. 180 - 63 = 117
then you do 117 + 43 = 160, then 160 divided by 5 = 32
which means that 5(32) - 43 = 117, 5 x 32 = 160 - 43 = 117.

Step-by-step explanation:
What is the value of X in this triangle?
Answer:
x = 3
Step-by-step explanation:
An equilateral ∆ has equal side lengths and all its angles are also equal to each other, which are 60° each.
The ∆ given has equal side lengths. Therefore it is an equilateral ∆ having equal angles, each would measure 60°.
Thus:
(25x - 15) = 60°
Solve for x
25x - 15 = 60
Add 16 to both sides
25x - 15 + 15 = 60 + 15
25x = 75
Divide both sides by 25
25x/25 = 75/25
x = 3

find the difference (20m+3)-(7m-5)
Answer:
Simplifying
(20m + 3) + -1(7m + -5) = 0
Reorder the terms:
(3 + 20m) + -1(7m + -5) = 0
Remove parenthesis around (3 + 20m)
3 + 20m + -1(7m + -5) = 0
Reorder the terms:
3 + 20m + -1(-5 + 7m) = 0
3 + 20m + (-5 * -1 + 7m * -1) = 0
3 + 20m + (5 + -7m) = 0
Reorder the terms:
3 + 5 + 20m + -7m = 0
Combine like terms: 3 + 5 = 8
8 + 20m + -7m = 0
Combine like terms: 20m + -7m = 13m
8 + 13m = 0
Solving
8 + 13m = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + 13m = 0 + -8
Combine like terms: 8 + -8 = 0
0 + 13m = 0 + -8
13m = 0 + -8
Combine like terms: 0 + -8 = -8
13m = -8
Divide each side by '13'.
m = -0.6153846154
Simplifying
m = -0.6153846154Step-by-step explanation:
Answer:
(20m+3)-(7m-5).
(20m-7m)+(3+5).
13m(8). =104m

Remy has $150 to spend on party supplies. She spends $75.50 on decorations and various other supplies. She spent the remaining money to order invitations. If she invited 20 people to her party, how much was the cost to print each invitation?
Answer:
the cost to price of each invitation is $3.725
Step-by-step explanation:
Given that
On party supplies she incurred $150
For decorations and various other supplies she incurred $75.50
The remaining amount i.e.
= $150 - $75.50
= $74.50
This amount would be incurred for the invitations
Now she invited 20 people
SO the cost to price of each invitation is
= $74.50 ÷ 20 people
= $3.725
Hence, the cost to price of each invitation is $3.725

23. is divisible by 9
Step-by-step explanation:
A number is divisible by 9 if the sum of its digits is divisible by 9. The process of reducing the sum of digits to a single digit is called "casting out nines." It can be a useful process for checking arithmetic of all sorts.
A number is divisible by 3 if the sum of its digits is divisible by 3.
__
22. 114 is divisible by 3 because 1+1+4 = 6, a number divisible by 3. Everyone will have a spot.
__
24. 2187 has a sum of digits of 2+1+8+7 = 18, which has a sum of digits of 1+8=9. This is divisible by 9, so 2187 is divisible by 9.
