Travel in a straight path with constant velocity as the rock doesn't want to break its inertial frame.
Explanation:
From the experiment:
Number of protons = 74
Number of neutrons = 110
Number of protons in an element is the atomic number of the element. It is used to locate and position and element on the periodic table.
For a neutral or uncharged atom, the number of protons is the same as the number of electrons.
The element whose number of protons or atomic number if 74 is Tungsten
Mass number = 74 + 110 = 184g/mol
Answer:
Condition of fatigue caused by depletion of glycogen
Explanation:
Let us examine how a body produces energy. There are two ways:
Fat metabolism
Fatty acids in the body help to capture adenosine triphosphate (ATP) which produces energy. On a per gram basis fatty acids yields the most ATP when oxidized completely.
Glycogen breakdown
the enzyme glycogen phosphorylase cleaves glycogen from the non reducing ends to produce monomers of glucose-1-phosphate. These monomers are used by the human body to supply energy.
When a person is exercising his/her VO₂ i.e., the oxygen consumption reaches maximum, here most of the energy comes from glycogen. While exercising most of the energy comes from glycogen breakdown.
So, when Anthony hit the wall it means that he has depleted his source of glycogen and can no longer produce glucose which provides him energy.
Forces equal the flag doesn't move either direction
Unequal forces the flag moves in the direction of the greater magnitude force
Answer:
θ = 12.95º
Explanation:
For this exercise it is best to separate the process into two parts, one where they collide and another where the system moves altar the maximum height
Let's start by finding the speed of the bar plus clay ball system, using amount of momentum
The mass of the bar (M = 0.080 kg) and the mass of the clay ball (m = 0.015 kg) with speed (v₀ = 2.0 m / s)
Initial before the crash
p₀ = m v₀
Final after the crash before starting the movement
= (m + M) v
p₀ =
m v₀ = (m + M) v
v = v₀ m / (m + M)
v = 2.0 0.015 / (0.015 +0.080)
v = 0.316 m / s
With this speed the clay plus bar system comes out, let's use the concept of conservation of mechanical energy
Lower
Em₀ = K = ½ (m + M) v²
Higher
= U = (m + M) g y
Em₀ =
½ (m + M) v² = (m + M) g y
y = ½ v² / g
y = ½ 0.316² / 9.8
y = 0.00509 m
Let's look for the angle the height from the pivot point is
L = 0.40 / 2 = 0.20 cm
The distance that went up is
y = L - L cos θ
cos θ = (L-y) / L
θ = cos⁻¹ (L-y) / L
θ = cos⁻¹-1 ((0.20 - 0.00509) /0.20)
θ = 12.95º
