Progressive overload is the gradual increase in stress to which we subject the body during training, where time, intensity and frequency are dimensions of it.
What is progressive overload?It is a training principle that emphasizes a progressive intensification of stress on the muscles.
It involves the systematic application of training stimuli that force the body to adapt and grow by manipulating the variables of frequency, time and intensity.
Therefore, we can conclude that progressive overload is the gradual increase in stress to which we subject the body during training, where time, intensity and frequency are dimensions of it.

What is the overall energy transformation in a coal-fired power plant?.
Answer: thermal energy, mechanical energy and, finally, electrical energy.
Explanation:
As a type of thermal power station, a coal-fired power station converts chemical energy stored in coal successively into thermal energy, mechanical energy and, finally, electrical energy. The coal is usually pulverized and then burned in a pulverized coal-fired boiler.

b. The silica cylinder of a radiant wall heater is 0.6 m long
and has a radius 6 mm. If it is rated at 1.5 kw estimate
its temperature when operating. [The Stefan constant,
6=6 x 10-8 wm-2-4)
Ans: 1025 K
So, If the silica cyliner of the radiant wall heater is rated at 1.5 kw its temperature when operating is 1025.3 K
To estimate the operating temperature of the radiant wall heater, we need to use the equation for power radiated by the radiant wall heater.
Power radiated by the radiant wall heaterThe power radiated by the radiant wall heater is given by P = εσAT⁴ where
ε = emissivity = 1 (since we are not given), σ = Stefan-Boltzmann constant = 6 × 10⁻⁸ W/m²-K⁴, A = surface area of cylindrical wall heater = 2πrh where r = radius of wall heater = 6 mm = 6 × 10⁻³ m and h = length of heater = 0.6 m, and T = temperature of heaterSince P = εσAT⁴
P = εσ(2πrh)T⁴
Making T subject of the formula, we have
Temperature of heaterT = ⁴√[P/εσ(2πrh)]
Since P = 1.5 kW = 1.5 × 10³ W
Substituting the values of the variables into the equation, we have
T = ⁴√[P/εσ(2πrh)]
T = ⁴√[1.5 × 10³ W/(1 × 6 × 10⁻⁸ W/m²-K⁴ × 2π × 6 × 10⁻³ m × 0.6 m)]
T = ⁴√[1.5 × 10³ W/(43.2π × 10⁻¹¹ W/K⁴)]
T = ⁴√[1.5 × 10³ W/135.72 × 10⁻¹¹ W/K⁴)]
T = ⁴√[0.01105 × 10¹⁴ K⁴)]
T = ⁴√[1.105 × 10¹² K⁴)]
T = 1.0253 × 10³ K
T = 1025.3 K
So, If the silica cylinder of the radiant wall heater is rated at 1.5 kw its temperature when operating is 1025.3 K

A bike first accelerates from 0.0m/s to 5.0m/s in 4.5s, then continues at this constant speed for another 4.5s. What is the total distance traveled by the bike
Initial speed u= 0.0 m/s
Final speed v= 5.0 m/s
Time t1= 4.5s
Time for constant speed t2=4.5s
to calculate the total distance traveled by the bike:d = d₁ + d₂
1 = ( v+u/2) × 1₁ + v × 1₂
v = final speed
u = initial speed
t₁ = time for first accelerates
t2 = time for constant speed
d = (5+0/2) × 4.5+ 5.0 x 4.5
d = 33.75m
so, the total distance traveled by the bike is 33.75 m.
# 1
[tex]\bold{a = \frac{(5-0)}{4.5} = 1.11 m/s^2 }[/tex]

If the pressure exerted by the liquid of density 500kg/m3 is 20,000Pa. What is height of liquid column.
The height of the liquid column is 4.08 metres.
The peak of the liquid column is 4.08 metres.
What's strain exerted with the aid of a liquid?As we realize that any liquid exerts a strain at a factor relies upon on the density of the liquid and the vertical intensity. depth is given = h and the acceleration because of gravity is g.
calculation:-
pressure = ρgh
ρ = density of the liquid
g = accaleration due to gravity
h = depth from the surface
l = 500kg/m3
p = 20,000
g = 9.8 ms-2
20,000Pa= 500*9.8*h
h=4.08m
What's the stress density?The stress is the measure of pressure acting on a unit region. Density is the measure of the way intently any given entity is packed, or it is the ratio of the mass of the entity to its extent. The relation between strain and density is direct. exchange in stress will be contemplated in a exchange in density and vice-versa.

Which of the following is a consequence of the special theory of relativity?
A) A moving object's mass is constant regardless of its speed.
B) Time slows as the speed of an observer's frame of reference increases
C) A stretching of time due to a moving object can be seen under normal conditions
D) It is possible for an object with mass to travel at the speed of light.
Answer:
D.
Explanation:
Specifically, Special Relativity showed us that space and time are not independent of one another but can be mixed into each other and therefore must be considered as the same object, which we shall denote as space-time. The consequences of space/time mixing are: time dilation. and length contraction.
A gyroscope flywheel of radius 2.12 cm is accelerated from rest at 16.2 rad/s2 until its angular speed is 1820 rev/min. (a) what is the tangential acceleration of a point on the rim of the flywheel during this spin-up process
The tangental acceleration of the flywheel of radius 2.12 cm with a final angular velocity of 1820 rev/min and an angular acceleration of 16.2 rad/s is 0.34 m/s².
What is tangental acceleration?This is the rate of change of tangental velocity of an object in circular motion.
To calculate the tangental acceleration, we use the formula below.
Formula:
a = αr............. Equation 1Where:
a = Tangental accelerationr = radius of the flywheelα = Angular acceleration of the flywheel.From the question,
Given:
r = 2.12 cm = 0.0212 mα = 16.2 rad/s²Subsitute these values into equation 1
a = (0.0212×16.2)a = 0.34 m/s²Hence, The tangental acceleration of the flywheel of radius 2.12 cm with a final angular velocity of 1820 rev/min and an angular acceleration of 16.2 rad/s is 0.34 m/s².

A 2.3-kg toy locomotive is pulling a 1.4-kg caboose. The frictional force of the track on the caboose is 0.46 N backward along the track. If the train is accelerating forward is 3.1 m/s2, what is the magnitude of the force exerted by the locomotive on the caboose
The net vertical force on the caboose (C) is
∑ F[v, C] = F[n, C] - (1.4 kg) g = 0
where F[n, C] is the magnitude of the normal force exerted by the track on the caboose; so we have
F[n, C] = (2.3 kg) g = 13.72 N
which means the coefficient of kinetic friction µ between the caboose and the track is
F[f, C] = 0.46 N = µ (13.72 N) ⇒ µ = (0.46 N) / (13.72 N) ≈ 0.034
and presumably the coefficient is the same for the locomotive.
The net vertical force on the locomotive (L) is
∑ F[v, L] = F[n, L] - (2.3 kg) g = 0
where F[n, L] is the magnitude of the normal on the locomotive, so that
F[n, L] = (2.3 kg) g = 22.54 N
and so the locomotive is opposed by a frictional force with magnitude
F[f, L] = µ (22.54 N) ≈ 0.76 N
Taking the locomotive and caboose together, the net horizontal force on the system is
∑ F[h] ≈ - F[f, C] - F[f, L] + F[engine] = (2.3 kg + 1.4 kg) (3.1 m/s²)
Solve for F[engine] :
F[engine] ≈ (3.7 kg) (3.1 m/s²) + 0.46 N + 0.76 N ≈ 13 N

Revolution and rotation are the terms that describe the different movements of the earth.
What is the earth?Our home planet is Earth. Earth and its moon, according to scientists, originated about the same period as the rest of the solar system.
That would have been around 4.5 billion years ago, according to scientists. Earth is the solar system's fifth-largest planet.
The rotation and revolution of the earth are two different movements. The movement of the earth on its axis is known as rotation.
Revolution is the movement of the earth around the sun in a fixed route or orbit. The earth's axis, which is an imaginary line, forms a 6612° angle with its orbital plane.
