What is frequency measured in? What is the amplitude?
Answer:
The units of frequency are hertz. As 1 hertz is equal to one cycle per second.
Amplitude is the maximum displacement of the waves or the distance from rest to crest and is measured in meters or centimeters or millimeters.
How do you choices of physical activities and food affect your fitness levels and health goals?
Answer:
Food provides energy for physical activity
Explanation:
As you get more active and more fit, and/or as you lose weight, your energy needs (how many calories you need) may change. To get the energy you require, you need to get the proper amount of: Protein, which is needed to maintain and rebuild tissues such as muscles.

A. 1 newtons B. 10 newtons
C. 100 newtons D. 1,000 newtons
Answer:
C. 100 NEWTONS
Explanation:
just my brain being ly = brainly is the name so my brian is being ly
The weight of the stone is 10N.
To find the weight of the stone, we need to know about the gravitational force on any object due to earth.
What is gravitational force?Gravitational force is a attractive force that arises between any two objects. The objects, on the earth surface or near the earth surface, experience the gravitational force of earth. This gravitational force is Known as the weight of the object. How can we calculate the gravitational force or the weight of an object, when it's near the earth surface?When an object is near the earth surface, its weight is mass × gravitational acceleration (g).
So, the weight of the stone= 1kg × 10 m/s²
= 10 N
Thus, we can conclude that the weight of the stone 100 m above a gorge is 10N.

When you describe a liquid as thick, are you saying that it has a high or a low viscosity?
The liquid with greater thickness will be more viscous since it flow speed is lower. Therefore, the more thick liquids is more viscous and flow slowly.
What is viscosity ?Viscosity of a liquid is the resistance to its flow. Viscosity depends on the density and thickness of the liquid. The more thicker the liquid the more viscous it will be.
Less thick liquids will flow fastly. For example water is a less viscous liquid as we see it flow so quickly. Whereas, honey, oil, etc are more viscous and the mobility of their liquid particles are resisted by viscosity.
The more viscous liquids generally has higher specific heat capacity as in the case of water and oil. The particle - particle attractive force is higher in highly viscous liquids.

Explanation:
The tallest volcano on Mars
A
is three times the height of Mt. Everest.
B
is almost as tall as Mt. Everest.
C
has been visited 44 times.
D
is wet, rocky and cold.
Answer: Is three times the height of Mt. Everest
Explanation:
Using the process of elimination we can rule out “D” Because its a volcano, C because it says we have visited mars 44 times not the volcano, B because in the passage is literally says “3 times the size of Mt. Everest”.
What combination for distance and mass gives you the STRONGEST or LARGEST force?
Answer:Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.
Explanation:
how can you reduce the percentage uncertainty in measurements that you make?
Answer:
you can decrease the uncertainty by making the same measurement multiple times and taking the average.
Explanation:
Within a period of the periodic table, how do the properties of the elements vary?
Answer:
Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
Explanation:
The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. ... They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus. When these heavy elements form, they are usually highly unstable.
A ball is thrown straight up from the ground with an unknown velocity. It returns to the ground after 4.0 s. With what velocity did it leave the ground?
Answer:
It must return at the same velocity with which it was thrown or else there would be a preferred direction of motion leading to perpetual motion.
a = (v2 - v1) / t = (v2 - 0) / 2 = v2 / 2 for a falling object
v2 = 2 a = 2 sec * 9.8 m/sec^2 = 19.6 m/s
You can check with
H = V0 t - 1/2 g t^2 (V0 and g are in different directions)
H = 0
V0 = 1/2 g * 4 = 19.6 m/s
A) half as much
B) as much
C) two times as much
D) three times as much
Answer:
3 times as much
Explanation:
half as much would be 12%, as much would be 24%, and two times as much would be 48%.
3 times as much is 72, which is about 74%

I don't understand this QUESTION
This electric force calculator will enable you to determine the repulsive or attractive force between two static charged particles. Continue reading to get a better understanding of Coulomb's law, the conditions of its validity, and the physical interpretation of the obtained result.
How to use Coulomb's law
Coulomb's law, otherwise known as Coulomb's inverse-square law, describes the electrostatic force acting between two charges. The force acts along the shortest line that joins the charges. It is repulsive if both charges have the same sign and attractive if they have opposite signs.
Coulomb's law is formulated as follows:
F = keq₁q₂/r²
where:
F is the electrostatic force between charges (in Newtons),
q₁ is the magnitude of the first charge (in Coulombs),
q₂ is the magnitude of the second charge (in Coulombs),
r is the shortest distance between the charges (in m),
ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N·m²/C². This value is already embedded in the calculator - you don't have to remember it :)
Simply input any three values
