Answer:
False
Explanation:
Low humidity is typically associated with cold temperatures since cold air holds less water compared to warm air. While it is possible for indoor humidity to be as low as 10%, most people generally find humidity levels of about 40 to 45 percent comfortable.

A marble is given potential energy by being placed by a location w. When the marble is released it rolls down the track at which location dose the marble have maximum kinetic energy w x or y or z
Answer:
The answer is "Location Y"
Explanation:
Please find the complete question in the attachment.
As we show in the graph when the marble rolling with the full force it will stop on the y location because it is curved, and the marble can't move to another location, that's why the maximum kinetic energy of the marble is at the y location.
The temperature of a substance is 45 C. Convert this to Kelvin.

I think A but I dont really know
Can someone help me in this please any one good in science.
Let's calculate the equivalent resistances on both circuits.
On Diagram A we have a series connection of the resistors. The equivalent resistance will be the sum of all resistances:
[tex]R_{eq}=1+1+1\\\\\boxed{R_{eq}=3\Omega}[/tex]
On diagram B we have a parallel connection of the resistors. The reciprocal of the equivalent resistance will be the sum of the reciprocals of all the resistances:
[tex]\frac{1}{R_{eq}} = \frac{1}{1} +\frac{1}{1} +\frac{1}{1} \\\frac{1}{R_{eq}}=3\\\\\boxed{R_{eq}=\frac{1}{3}}[/tex]
Therefore, the larger resistance occurs on diagram A.
For the current, recall
[tex]V=IR[/tex]
Where [tex]I[/tex] stands for current [tex]R[/tex] is the resistance and [tex]V[/tex] is the voltage. Rearranging the equation we have
[tex]I = \frac{V}{R}[/tex]
We can see that the larger the resistance, the smaller the current gets. So the larger current must happen in the diagram with smaller resistance. Therefore, the larger current occurs on diagram B.
Glad to help, wish you great studies ;)

If you are test-driving a Bugatti Veyron and you go from 0 m/s to 124 m/s in 3.7 seconds, what was your acceleration?
Answer:
initial velocity (u) = 0 m/s
Final velocity (v) =124 m/s
Time (t) = 3.7 s
acceleration (a) =?
Now
A =V-U /T
= 124-0 /3.7
= 33.51 m/s^2
A 1 kg puck sliding on a horizontal shuffleboard court is slowed to rest by 1 point
a frictional force of 3 N. What is the coefficient of kinetic friction between
the puck and the surface of the shuffleboard court? *
O A. 0.25
O B.0.5
O c.0.15
D. .31
Answer:
miu = 0.31
Explanation:
The friction force is defined as the product of the normal force by the coefficient of friction.
[tex]f=miu*N[/tex]
where:
f = friction force = 3 [N]
miu = friction coefficient
N = normal force [N]
The normal force on a horizontal surface can be calculated by means of the product of mass by gravity.
where:
m = mass = 1 [kg]
g = gravity acceleration = 9.81 [m/s²]
[tex]N=m*g\\N=1*9.81[/tex]
[tex]N= 9,81 [N][/tex]
Now replacing in the equation above, we can find the friction coefficient.
[tex]miu=3/9.81\\miu = 0.31[/tex]
A cyclist acceleration from 0m/s to 8m/s in 3second. what is his acceleration?
Answer:
2.66 m/s² .
Explanation:
Initial velocity , u = 0 m/s
Final Velocity , v = 8 m/s
Time Taken , t = 3 s
So , Acceleration = (v-u)/t = (8 m/s - 0 m/s) /3 sec . = 8/3 m/s² = 2.66 m/s²

If you were to mix 7 grams of sugar into 100 grams of water, how much should the total mass of the solution be?
95 grams
100 grams
93 grams
107 grams
Answer:
The total mass of the solution should be 107 grams
Explanation:
Solutions
A solution is a homogeneous mixture consisting of a solute dissolved into a solvent. The solute is the substance that is being dissolved, while the solvent is the dissolving medium.
The relationship between the masses is:
[tex]m_s=m_o+m_v[/tex]
Where:
ms = mass of the solution
mo = mass of the solute
mv = mass of the solvent
If you were to mix mo=7 gr of sugar into mv=100 gr of water, then the total mass of the solution should be:
[tex]m_s=7~gr+100~gr[/tex]
[tex]m_s=107~gr[/tex]
The total mass of the solution should be 107 grams
What does a curved gradient line in a distance-time graph represent?
Answer:
If the line is curved, the slope is changing, which also means the velocity is changing. In a distance-time graph, the gradient of the line is equal to the speed of the object. The more the gradient (and the steeper the line) the faster the object is moving.
A billiard ball traveling at 4m/s has an elastic head-on collision with a billiard ball of equal mass that is initially at rest. The first ball is at rest after the collision. What is the speed of the second ball after the collision?
Answer:
The speed is 4m/s because the size is the same.
Explanation:
The speed of the second ball after the collision is 4 m/s.
What is law of conservation of momentum?According to the law of conservation of momentum, The overall momentum of two or more bodies acting on one another in an isolated system stays constant unless an external force is introduced. As a result, momentum cannot be gained or lost.
Let the mass of each billiard ball is m.
Before collision speed of first billiard ball: u = 4 m/s.
Before collision speed of second billiard ball: U= 0 m/s.
After collision speed of first billiard ball: v = 0 m/s.
After collision speed of second billiard ball: V= ?
From conservation of momentum, we can write:
Total momentum before collision = Total momentum after collision
mu +M.0 = m.0 + m.V
u = V
V = 4 m/s.
The speed of the second ball after the collision is 4 m/s.
