Answer:

Force, F = 1 N

Explanation:

We have

Mass of a box is 1 kg

Acceleration with which it is pushed is 1 m/s²

It is required to find the force acting on the box.

Force, F = ma

[tex]F=1\ kg\times 1\ m/s^2\\\\F=1\ N[/tex]

So, the force of 1 N is acting on the box.

Answer:

The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist.

As the burning of fossil fuels and landscape alterations, such as deforestation and industrial agriculture, mobilize fossil carbon into the atmosphere, the earth's carbon cycle is pushed out of balance and climate changes. Human generated climate change is an enormous perturbation in the global carbon cycle.

Fever or elevated body temperature might be caused by:

A virus.

A bacterial infection.

Heat exhaustion.

Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)

A malignant tumor.

Many illness-causing microbes do best at the body's normal temperature. A fever raises the temperature beyond which certain microbes need to reproduce. A fever also kicks your child's immune system into high gear, spurring the rapid production of bug-clobbering white blood cells.

The outbreak of tornadoes that tore across the Gulf and the East Coast Tuesday and Wednesday was unusual for two reasons. For one thing, the severe weather encompassed a significant swath of the country. For another, winter is the least likely time for tornadic thunderstorms.

Explanation:

The outbreak of tornadoes that tore across the Gulf and the East Coast Tuesday and Wednesday was unusual for two reasons. For one thing, the severe weather encompassed a significant swath of the country. For another, winter is the least likely time for tornadic thunderstorms.

And yet tornadoes are an expected part of life in the United States—especially in the multi-state area known as Tornado Alley. (Florida, too, sees a disproportionately high number of tornadoes, because of its frequent thunderstorms.) The United States gets more tornadoes, by far, than any other place on the planet. It averages about 1,250 twisters a year. Canada, which sees about 100 tornadoes per year, is a “distant second,” according to the National Centers for Environmental Information.

Answer:

The initial velocity of the second stone is 34.3 m/s

Explanation:

The distance height covered by the second stone will be

75m - 15m = 60 m

Since the two stones hit the ground at the same time.

Using third equation of motion, which state that;

V^2 = U^2 - 2gH

Where

U = Initial velocity

V = final velocity

H = 60 m

g = 9.81 m/s^2

As the stone reaching the ground, that is, coming to rest, V = 0. Therefore,

Substitute all the parameters into the equation

0 = U^2 - 2 × 9.81 × 60

U^2 = 1177.2

U = 34.3 m/s

The initial velocity of the second stone is 34.3 m/s

Answer:

Explanation:

Answer:

1.) Total distance = 70 m

2.) Total displacement = +30m

Explanation:

Distance is a scaler quantity. That is, we will be concerned about its magnitude only and not direction.

Total distance = 10 + 20 + 40 = 70 m

While displacement is a vector quantity. We will consider both the magnitude and its direction.

Forward direction will be positive while backward direction will be negative

Total displacement = +10 - 20 + 40

Total displacement = +30 m

Answer:

3.60 × [tex]10^{15}[/tex] Hz

Explanation:

[tex]\frac{2.39 * 10^{-18} J}{6.63 * 10^{-34} J.s}[/tex]

The frequency of UV light that has an energy of 2.39 × 10 -18 J is 3.60 ×  Hz.

The term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

Moreover, frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity, and is distinct from angular frequency. Frequency is measured in hertz which is equal to one event per second.

Therefore, the number of vibrations that a sound wave is making is called its frequency ( f ). Frequency can also be defined as the number of waves passing a given point in one second. Frequency is measured in hertz (Hz).

Answer:

The two neighboring planets with the greatest distance between them is Neptune and Uranus. This happens when they are at the opposite sides of the Sun at approximately. They are 4500 million miles away from each other.

If by adjacent you mean next to each other, in terms of the order of planets in our Solar System, then the closest would be Earth and Venus; which are separated by about 38,000,000 kilometres when in opposition.

I am not sure about the general patterns..

Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days.

A year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days). It is obvious because it is also the farthest with the longest orbit.

Outer planets are less dense than the inner planets because they posses a big volume but contains not much mass. Try to imagine 2 rocks, one is big, but is hollow or have a lot of holes; and the other is small, but solid with no holes.

The charge applies only to the electric force.

Electrostatic force is directly related to the charge of each object. So if the charge of one object is doubled, then the force will become two times greater. Two times 0.080 N is 0.160 N.

Electric forces can only act between charged objects - either like-charged or oppositely-charged. Electric forces between two charged objects increase with increasing separation distance.

Answer: New frequency = 103.3Hz

Explanation:

Given that the

Frequency F = 116.5 Hz

The tube is an opened tube.

The relationship between wavelength and the length of the tube is

λ = 2L/n

Where

λ = wavelength

L = length of the tube

n = number of harmonic

For 4th harmonic,

λ = 2L/4 = L/2

But wave speed V = F(λ)

Substitutes (λ) into the wave speed formula

V = FL/2

Let's assume that the V is the speed of sound = 330m/s

Substitutes the V and F into the formula above.

330 = 116.5L/2

Cross multiply

660 = 116.5L

L = 660/116.5

L = 5.67 m

Given that the first valve is pushed, it opens an extra bit of tubing 0.721m long.

New length = 5.67 + 0.721 = 6.39 m

New frequency will be

330 = 6.39F/2

Cross multiply

660 = 6.39F

F = 660/6.39

F = 103.3 Hz
