Radiative forcing is the amount of change in the thermal energy units (watts/square meter on the earth's surface) caused by a given factor. True or False?

Answers

Answer 1
Answer:

Answer:

True

Explanation:

Radiative forcing is indeed the measure of the change in thermal energy units (watts per square meter) at the Earth's surface or in the atmosphere caused by a particular factor, such as an increase in greenhouse gases or aerosols. It quantifies the impact of various factors on the Earth's energy balance and is an important concept in climate science for understanding the drivers of climate change.

If you were to throw flour on the man in the photo, the flour would stick to the man's chest everywhere but on his scar. Why?

Answers

Explanation:

Flour typically sticks to surfaces due to adhesive forces, and it's more likely to stick to areas with moisture or oils on the skin. If the scar on the man's chest lacks moisture or oils (which is common for scars), the flour may have difficulty adhering to that specific area. However, it could stick to the surrounding skin where there might be more moisture or natural oils.

Which of the following groups of environmental science careers are most similar?a. Hydrologist, toxicologist, environmental lawyer
b. Environmental physician, environmental veterinarian
c. Environmental activist, oceanographer, ecologist
d. Oceanographer, Environmental journalist

Answers

The correct answer for the question that is being presented above is this one: "b. Environmental physician, environmental veterinarian." The groups of environmental science careers that are most similar is that of Environmental physician and environmental veterinarian.

Correct answer choice is:

B. Environmental physician, environmental veterinarian.

Explanation:

Environmental medicine is a field involving several academic disciplines including physicians, environmental science, chemistry and many other related fields, protruding with environmental diagnostics. The extent of this domain includes examining the interplay's between ecosystem and human health, and the role of the atmosphere in producing or negotiating infection. Likewise, In the wildlife division, doctors are frequently defied with the outcomes of environmental contaminants and contagious infection disorders that probably endanger wild and housebroken animals as well as individuals.

What is the average speed of a car that traveled 300.0 miles in 5.5 hours?

Answers

The average speed of will be "0.41 m/s".

Speed and Distance:

According to the question,

Distance = 300.0 miles

Time = 5.5 hours

We know,

300.0 miles = 482803 meters

Now,

By converting 5.5 hours into seconds, we get

= 5.5* (60)/(1)* (3600)/(1)

= 1,188,000

hence,

The speed will be:

= (482803)/(1188000)

= 0.406 or, 0.41 \ m/s

Thus the above answer is right.

Answer:

54.54 miles per hour

Explanation:

You do 300 divided by 5.50 to get 54.545454 but you can estimate it to be about 54.54 miles per hour.

So, top average speed of car was 54.54 mph.

a ball has mass of 0.1 kg and an initial velocity of 20 m/s the ball is given an acceleration of 30 m/s^2 for 5s what is the net force on the ball during acceleration

A solid sphere has a radius of 0.200 m and a mass of 150.0 kg. how much work is required to get the sphere rolling with an angular speed of 50.0 rad/s on a horizontal surface? assume that the sphere starts from rest and rolls without slipping.

Answers

Here in this case we can use work energy theorem

As per work energy theorem

Work done by all forces = Change in kinetic Energy of the object

Total kinetic energy of the solid sphere is ZERO initially as it is given at rest.

Final total kinetic energy is sum of rotational kinetic energy and translational kinetic energy

KE = (1)/(2)Iw^2 +(1)/(2) mv^2

also we know that

I = (2)/(5)mR^2

w= (v)/(R)

Now kinetic energy is given by

KE = (1)/(2)((2)/(5)mR^2)w^2 +(1)/(2) m(Rw)^2

KE = (1)/(5)mR^2w^2 +(1)/(2) mR^2w^2

KE = (7)/(10)mR^2w^2

KE = (7)/(10)*150*(0.200)^2(50)^2

KE = 10500 J

Now by work energy theorem

Work done = 10500 - 0 = 10500 J

So in the above case work done on sphere is 10500 J
