The physics conservation of energy E = 39.2 joules.
Mass of the block, m = 5 kg
At the top, the block will have only potential energy which is given by :
P=mgh
At the bottom of the inclined plane, it will have only kinetic energy which is given by :
E=(1/2)mv2
Applying the conservation of energy as :
E=(1/2)mv2=mgh
E=5*9.8*0.8
E = 39.2 joules.
The physics conservation of energy E = 39.2 joules.

Answer:
θ = 19.47°
Explanation:
given,
mass of the barge = 1000 kg
force applied to pull = 80 N
direction = 30° west to north
force exerted by the cable = 120 N
direction = ?
first cable is pulling
in north direction = 80 cos ∅
= 80 cos 30°
= 69.28 N
in west direction = 80 sin ∅
= 80 sin 30°
= 40 N
the other cable will pull in the opposite direction of west
now,
θ = 19.47°
the direction of the cable will be equal to θ = 19.47°
B)0.944
C)1.21
D)1.06
The equation for the index of refraction is n = sin(theta1)/sin(theta2) where theta1 is the refracted angle and theta2 is the angle in a medium. Plugging in the values for the index of refraction, n = sin(32)/sin(26) we get 1.21. the answer is letter C. The index of refraction is always greater than 1.
That answer is wrong it is not 1.21 just turned it in and was wrong
b. Rubber tape
c. Cotton tape
d. Plastic tape
Answer:
Explanation:
the answer is rubber tape not friction tape
b. electron transport
c. glycolysis
d. Krebs cycle
Fermentation is the stage where it is not part of the cellular respiration. The answer is letter A. fermentation does not require oxygen to do respiration, rather, these are the glycolysis, Kreb’s cycle and electron transport.
Fermentation is NOT a stage of cellular respiration. Therefore option A is correct.
Fermentation is not a stage of cellular respiration. Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP (adenosine triphosphate).
It occurs in three main stages: glycolysis, the Krebs cycle (also known as the citric acid cycle or the tricarboxylic acid cycle), and the electron transport chain.
Fermentation is an alternative metabolic pathway that occurs in the absence of oxygen (anaerobic conditions). It is a partial breakdown of glucose or other organic molecules that do not involve the complete oxidation of glucose to produce ATP.
Instead, it produces a small amount of ATP and end products such as lactic acid or ethanol.
Therefore option A is correct.

Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth.
C.
Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves do not require a medium to travel; therefore, light travels through the vacuum of space to be seen on the earth.
D.
Light from the stars is visible light and travels as surface to surface waves. Surface waves require a medium to travel; therefore, light travels from the surface of the star to the surface of the earth.
