Write a 5-8 sentence summary on Earthquakes.
Answer:
An earthquake is a sudden shaking movement of the surface of the earth. It is known as a quake, tremblor or tremor. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities. ... An earthquake is measured on Richter's scale.
PLEASE MARK ME BRAINLIEST, PLEASEHow are humidity and precipitation related?
A. When humidity is low, the chance of precipitation is high.
b.When humidity is high, the chance of precipitation is high.
c.When humidity is high, the chance of precipitation is low.
d.Changes in humidity do not cause precipitation.
Answer:
Relative humidity depends on the amount moisture actually in the air at some temperature to the amount of moisture that the air can hold.
For instance, at 25 deg C the air has a saturation pressure of 23.76 mm of Hg.
That means that if at that temperature the pressure of the water vapor in the air reaches 23.76 mm Hg then the air is 100% saturated.
I believe the standard air pressure at 25 deg C is 760 mm Hg.
Now if the pressure of the water vapor in the air is 1/2 * 23.76 = 11.88 mm then the air is 50% saturated and the relative hunidity is 50 %.
At 100% relative humidity rain occurs (the air can't hold any more water).
When humidity is high, the chance of precipitation is high. The correct answer is b. When humidity is high, the chance of precipitation is high.
The amount of moisture or water vapor in the air is referred to as humidity. Relative humidity is a common way to measure it since it shows how much moisture the air is holding relative to how much it could contain at a particular temperature.
Any type of water that falls from the atmosphere and makes it to the surface of the Earth is referred to as precipitation. Examples include rain, snow, sleet, and hail.
When humidity levels are high, there is a lot of moisture in the air, which increases the possibility that saturation will occur. Excess water vapor condenses into visible water droplets or ice crystals as the air gets saturated, creating clouds. Condensed moisture in the clouds eventually gains enough weight to return to Earth as precipitation.
Therefore, when humidity is high, the chance of precipitation is high. The correct answer is:
b. When humidity is high, the chance of precipitation is high.

The isotopes of any element have same number of protons inside them.
What is Cadmium?Cadmium is a chemical element with the symbol Cd and atomic number 48. It is soft, silvery and white metal.
Given is about Cadmium that it has eight naturally occurring isotopes.
Isotopes are the atoms of the same element which have same number of protons in them but the number of neutrons are different. Isotopes usually have same chemical properties, but they have different physical properties. Their can be stable and unstable isotopes. These unstable isotopes are also called radioisotopes, since they emit radiation. Thus, the isotopes have same number of protons.
Therefore, the isotopes of any element have same number of protons inside them.

Given the following situation of marble in motion on rolling 10 m/s horizontally from a height of 1.5-m with negligible friction.
a.) Once the ball leaves the table, calculate how long it will take for the ball to hit the floor?
b.) How far will the ball travel horizontally before hitting the floor?
Answer:
The ball would hit the floor approximately [tex]0.55\; \rm s[/tex] after leaving the table.
The ball would travel approximately [tex]5.5\; \rm m[/tex] horizontally after leaving the table.
(Assumption: [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].)
Explanation:
Let [tex]\Delta h[/tex] denote the change to the height of the ball. Let [tex]t[/tex] denote the time (in seconds) it took for the ball to hit the floor after leaving the table. Let [tex]v_0(\text{vertical})[/tex] denote the initial vertical velocity of this ball.
If the air resistance on this ball is indeed negligible:[tex]\displaystyle \Delta h = -\frac{1}{2}\, g\, t^{2} + v_0(\text{vertical}) \cdot t[/tex].
The ball was initially travelling horizontally. In other words, before leaving the table, the vertical velocity of the ball was [tex]v_0(\text{vertical}) = 0 \; \rm m \cdot s^{-1}[/tex].
The height of the table was [tex]1.5\; \rm m[/tex]. Therefore, after hitting the floor, the ball would be [tex]1.5\; \rm m \![/tex] below where it was before leaving the table. Hence, [tex]\Delta h = -1.5\;\rm m[/tex].
The equation becomes:
[tex]\displaystyle -1.5 = -\frac{9.81}{2} \, t^{2}[/tex].
Solve for [tex]t[/tex]:
[tex]\displaystyle t = \sqrt{1.5 \times \frac{2}{9.81}} \approx 0.55[/tex].
In other words, it would take approximately [tex]0.55\; \rm s[/tex] for the ball to hit the floor after leaving the table.
Since the air resistance on the ball is negligible, the horizontal velocity of this ball would be constant (at [tex]v(\text{horizontal}) =10\; \rm m \cdot s^{-1}[/tex]) until the ball hits the floor.
The ball was in the air for approximately [tex]t = 0.55\; \rm s[/tex] and would have travelled approximately [tex]v(\text{horizontal})\cdot t \approx 5.5\;\rm m[/tex] horizontally during the flight.
If Jay pushes on a box with a force of 20 N to the right and Bradley pushes on a box with a force of 15 N to the left, what is the net force on the box?
Answer:
Net force = 5N
Explanation:
Jay = 20N to the right
Bradley = 15N to the left
To find the net force;
Since the forces are being applied to the box in opposite direction i.e acting in opposite direction, we would subtract them.
Net force = 20 - 15
Net force = 5N
Therefore, the net force on the box is 5 Newton.

A clock which has a brass pendulum beats second correctly when the temperature of
the room is 30°c. It gains the time 15.55 sec per day when the temperature of the
rooms falls to 10°C. Find the linear expansivity of brass.
Answer:
- 0.0481666 °C^-1
Explanation:
Linear expansivity of brass, α
α = (2T - 2T0) / T0.dt
T0 = 30°
dt = change in temperature = 30 - 10 = 20°C
T = 15.55 sec
α = (2*15.55 - 2*30) / 30*20
α = (31.1 - 60) / 600
α = - 28.9 / 600
α = - 0.0481666 °C^-1

Three identical resistors have an equivalent resistance 15.6 ohm when they are connected in series. What is the resistance for each resistor
Answer:
5.2 Ω.
Explanation:
What is the resistance for each resistor
Since the resistors are connected in series and each have resistance R, and their equivalent resistance is R' = 15.6 Ω.
Since they are connected in series, R' = R₁ + R₂ + R₃
Since R₁ = R₂ = R₃ = R
R' = R + R + R = 3R
R' = 3R
R = R'/3
R = 15.6 Ω/3
R = 5.2 Ω
So, the resistance of each resistor is 5.2 Ω.

Mercury has a radius of 2.43x10^6 m, and a mass of 3.2x10^23 kg, what is Mercury's acceleration due to gravity?
I think that you need the gravitational acceleration of mercury
so we will use Newton's gravitational law :
gravitational acceleration = [tex]\frac{G * m}{r^{2} }[/tex]
G is the gravitational constant = G = 6.673×10^-11 N m^2 kg^-2
after substitution :
6.673×10^-11 * 3.2x10^23 / (2.43x10^6)^2
using calculator :
gravitational acceleration of mercury = 3.61625 m/s^2
