Answer:
The correct answer is the Mesosphere. Mesosphere is the layer of the Earth's atmosphere that is directly above the stratopause and directly below the mesopause.
Explanation:
Answer:
684J
Explanation:
So basically the formula for gravitational potential energy is Mass X Gravity X height. That is G.p.e = mgh
We don't have the mass but since we have the height, we multiply directly with the height since the quantity of weight is already given.
so G.p.e = 360 X 1.9 = 684J
Note that; The answer is in joules because g.p.e is work done.
Hope that was helpful!!
Work is the product of force multiplied by the distance moved, but since the distance moved in the vertical direction is zero
Work Done = 0 joules
Given data
Force = 125N
Horizontal Distance = 2 m
Vertical distance = 0 m
Work = Force * Distance
Solution
substitute the given information
Work Done in the horizontal direction= 125*2
Work Done = 250 Joules

Answer:
1.8 MJ
Explanation:
PE = mgh
PE = (1500 kg) (3.7 N/kg) (324 m)
PE = 1,798,200 J
PE = 1.8 MJ
Answer:
Explanation:
1) First of all, we need to calculate the heat needed to raise the temperature of the block of lead from the initial temperature (25.0 C) to the melting temperature (327.5 C). This heat is given by the equation
where
m = 2.00 kg is the mass of the block
Cpb = 130.0 J/kg*C is the specific heat capacity of lead
is the temperature difference
Substituting,
2) Now we have to calculate the amount of heat needed to completely melt the lead, which is given by:
where
Hj = 2.04x10^4 J/kg is the latent heat of fusion of lead
Substituting,
3) Therefore, the total heat needed is
Answer:
Q = 2.00kg x 130 J/kgC x 302.5C
Q = 7.87 x 10^4j
Q = 2.00kg x 2.04 x 20^4
Q= 4.08 x 10^4
Q = 7.87 x 10^4j + 4.08 x 10^4 = 1.2 x 10^5j

b. False
Correct answer choice is :
A) True
Explanation:
Lipoproteins are essentially a hub full of fat and cholesterol, along with a lipid layer that includes proteins named apolipoproteins. There are many kinds of lipoproteins, but the two most prominent ones are called Low-Density Lipoprotein and HDL.LDL particles are seldom related to as bad lipoprotein because of concentrations, dose-related, associated with atherosclerosis change. High-density lipoproteins (HDL) get fat molecules from the body's cells and take it back to the liver.
