A mountain climber increases their height from 200 meters to 400 meters. What affect will this have on their potential energy?
Answer:
At 400 m the potential energy of the mountain climber doubled the initial value.
Explanation:
Given;
initial height of the mountain climber = 200 m
final height of the mountain climber, = 400 m
The potential energy of the mountain climber is calculated as;
Potential energy, P.E = mgh
At 200 m, P.E₁ = mg x 200 = 200mg
At 400 m, P.E₂ = mg x 400 = 400mg
Then, at 400 m, P.E₂ = 2 x 200mg = 2 x P.E₁
Therefore, at 400 m the potential energy of the mountain climber doubled the initial value.

Two factors on which the frequency of the sound generated by a wind instrument depends...
The other factor that determines the frequency produced by a wind instrument is the speed at which the sound waves travel. Although typically about 343 m/s (at room temperature), the speed of sound does vary slightly with the temperature of the air, increasing as the temperature rises and decreasing as the air becomes colder.

Alisa, a skateboarder, is riding down a hill. If Alisa and the skateboard are considered a single object, what forces are acting on her? Check all that apply.
Answer: gravity
normal force
friction
Explanation:
A force is refered to as the interaction which when unopposed, will lead to a change in an objects motion. The velocity of an object will be changed when force is applied.
Since Alisa s riding down a hill and she and the skateboard are considered to be a single object, then the forces that are acting on her include gravity, normal force and friction.

6.There are four mixtures A, B, C and D. The mixture A contains sand and sugar, mixture B contain chalk powder and salt, mixture C contains salt and sugar, whereas mixture D contains sugar and charcoal powder. Which one of these mixtures cannot be separated by using water as a solvent? Why?
Answer:
Mixture C (salt and sugar)
Explanation:
Both salt and sugar can dissolve in water. And you can't just separate the mixture by filtering it like you could in the other mixtures.
HURRY PLS IM IN NEED. Question 14 of 16
Which chemical equation represents a synthesis reaction?
O A. 2Na+ MgCl2 - 2NaCl + Mg
B. C+02 - CO2
C. H2CO3 - H2O + CO2
OD. HCI + LiOH
LiCl + H20
Answer:
B: C + O2 = CO2
Explanation:
In Chemistry,a synthesis reaction is one that occurs when two or more reactants combine in such a manner that they form a single product.
Looking at the options, the only one where 2 reactants combine to form a single product is option C where Carbon reacts with Oxygen to form carbon (IV) oxide.

If u walk to school at a speed of 1.2 m/s and it takes you 18 min to reach the school, what is the distance from your home to the school?
Answer:
21.6m
Explanation:
Distance=speed×time
=1.2m/s×18min
=21.6m
Hope this helps u
Answer:
Explanation:
1 minute = 60 seconds
18 minutes = 18 * 60 sec = 1080 seconds
1 second allows 1.2 meters of a step
1080 second = x
1 / 1080 = 1.2 / x Cross multiply
x = 1.2 * 1080
x = 1296 meters
I live 1296 meters from the school.
When animals such as fox, deer and bears eat fruits from plants, the seeds are typically completely digested. True False
Answer:
False.

Density=2g/cm^2
Which identification and treatment model takes family environment into account for diagnosis and treatment?
If this question is the essay one the answer would be " The biopsychosocial model is the distinguishing proof and treatment model that considers family climate for conclusion and treatment. It takes a gander at both clinical and mental reasons for problems, and treats mental issues as cooperation of natural, mental, and sociocultural components. Family climate is considered as one of these sociocultural elements."
Can someone help me find the which direction is north and which is south on this solenoid?
Explanation:
Now, looking down the solenoid tube determine what direction is the winding. If clockwise in relation to the positive wire then is the south pole, if anti-clockwise then is the north pole. So, to summarize the magnetic south pole is always clockwise in relation to the positive wire.

Answer:
C option, when two atoms collide and they explode
Explanation:
Because the kinetic energy they have initially for collision will appear as final kinetic energy of the particles of atom after collision. Hence the kinetic energy is conserved so the collision will be elastic.

Which combination of quarks can NOT exist?
Answer:
So you can have quark anti-quark pairs (charge anti-charge), or add the charges together (red+blue+green = white). This also holds for theorectical particles made of 4 quarks (2 quarks 2 anti-quarks) and 5 quarks (four quarks and 1 anti-quark or the reverse). In your example ud only has two quarks so only two colour charges so cannot exist. If you want a more indepth answer start reading about colour charge.

Bruce has a momentum of 430kg m/s and is running at 7.8m/s. What is Bruce's mass?
Answer:
55.128kg
Explanation:
P= m×v
or, m=P/v = 430/7.8 = 55.128 kg
Answer:
55.13 kg
Explanation:
Momentum, P = m*v
P = m*v
m = P/v
m = 430/7.8
m = 55.13 kg
