On the other hand, Florida's Gulf Coast experiences the greatest number of thunderstorms out of any U.S. location. These types of storms occur on average 130 days per year in Florida.

Answer:

-The force of gravity must be broken into its parallel and perpendicular components.

-Acceleration can be found by dividing the net force by mass.

-Trigonometry can be used to solve for the magnitude of the force components.

Answer:20 miles

Explanation:

Explanation:

It is given that, a robot starts from a certain point and moves east for a distance of 5.0 meters, then goes north for 3.0 meters, and then turns west for 2.0 meters.

Let east is +x, west is -x north is +y.

When it moves east for a distance of 5.0 meters, it means (5,0)

When it goes north for 3.0 meters, and then turns west for 2.0 meters, it means (0,3) +(-2,0)

(a) x-y coordinates for the resultant vector is (3,3)

(b) The magnitude of the resultant vector for the robot is given by :

Answer:

when the ball is bounced gravitationally energy is released (more info below)

Explanation:

When a force is applied down to the ball, the gravitational potential energy is converted into kinetic energy before it hits the earth. Cinetic energy is converted into vibration, thermal, and static electrical energy, before the momentum of the ball pushes the ball back up into the hands of the people.

hope this helped!

The description of the mechanical energy and the thermal energy at the time when the ball should be bounded at the time when there is the realization of the gravitational energy.

At the time when the force is applied down to the ball so here the gravitational potential energy should be transformed into kinetic energy prior at the time when it should be hit to the earth. Kinetic energy should be transformed into vibration, thermal, and static electrical energy prior to the momentum of the ball that pushed the ball back up the hands of the people.

Answer:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Answer:

-0.375 m/s2

Explanation:

To find the acceleration due to gravity in this planet, we can use the Torricelli formula of UALM (uniformly accelerated linear motion):

V^2 = Vo^2 + 2*a*S

Where V is the final velocity, Vo is the inicial velocity, a is the acceleration and S is the total displacement.

With V = 3, Vo = 0 and S = -12, we have:

3^2 = 0^2 - 2*a*12

24a = -9

a = -9/24 = -0.375 m/s2

Answer:

A

Ultraviolet light occurs after white light;

Do you know why gamma rays are harmful because of their high frequency and short wavelength leading to high intensity.

Though the frequency is higher than that of white light, its because of its intensity.

Ultraviolet rays comes handy from depletion of the earth's ozone layer

Hence harmful Ultraviolet rays from the sun attacks the skin Leading to Sun burn and other things.

Answer:

High frequency is the answer

Answer:

It is 52° below the celestial equator.

Explanation:

The declination is the angle in degrees measured north (+) or south (-) of the an imaginary line called the celestial equator.

The celestial equator is a projection of the earth's equator on the celestial sphere. imaginary

The star named Canopus has a declination of approximately –52°.

Since the angle is negative, this shows that it is south or below the celestial equator and at 52° south of the celestial equator.

Thus, the star named Caponus is 52° below the celestial equator.

Answer:

the answer is 'it is 52° below the celestial equator.' :))

Answer:

Explanation:

Question 1:

Given;

a counterweight of mass, m = 2-kg

distance moved by this weight, d = 0.5 meters

the gravitational force of the counterweight is calculated as;

F = mg

where;

F is gravitational force

m is the mass

g is acceleration due to gravity

F = 2 x 9.8 = 19.6 N

Thus, the gravitational force of the counterweight is 19.6 N

Question 2:

Given;

a counterweight of mass, m = 2-kg

height moved by this weight, h = 0.5 meters

the work done is calculated as;

Work done = Force x distance moved by this weight

Work done = 19.6 x 0.5 = 9.8 J

Thus, the work done is 9.8 J

Answer:

Density equals mass over volume so 2 divided 500

friction

Explanation:

The property of matter that resists changes in motion is called friction. Details about friction can be found below.

Friction is a force that resists the relative motion of two bodies in contact.

Friction is a resisting force that is experienced when two bodies are moving over one another, hence, is said to resist changes in motion. Examples of cases of friction are as follows:

Therefore, the property of matter that resists changes in motion is called friction.

Answer:

due to the presence of fee electrons.

Explanation:

these electrons conduct electric current.

Conductivity in metallic solids is due to the presence of free electron. No of the electron will decide the flow of the electric current.

When the matter is put in an electromagnetic field, it has an electric charge, which causes it to experience a force. A positive or negative electric charge can exist.

Charges that are similar repel each other, whereas charges that are dissimilar attract each other. The term “neutral” refers to an item that has no net charge.

A valence electron is an electron in the outermost shell. Hence, associated with an atom that can experience the innovation of a chemical bond if the outer shell is not closed.

Conductivity in metallic solids is due to the presence of free electron.

Hence, electron is the correct answer for blank.

Answer:

a=1 m/s^2

Explanation:

[tex]a = \frac{v - u}{t} \\ = \frac{10 - 0}{10} \\ = 1m {s}^{ - 2} [/tex]

Hey!!

Solution,

Initial velocity(u)=0 m/s

Final velocity(v)=10m/s

Time(t)=10s

Acceleration=?

Now,

Acceleration=v-u/t

=10-0/10

= 10/10

=1 m/s^2

The acceleration is 1 m/s^2
