Output power of the solar panel is 170.6 W.
What is solar panel?Solar panels are those tools that take the sun's rays and turn them into heat or power.
An array of solar (or photovoltaic) cells make up a solar panel, which can be used to produce power thanks to the photovoltaic effect. On the surface of solar panels, these cells are organized in a grid-like configuration.
Given parameters:
Area of the solar panel: A = 1.25 m²
Efficiency of the solar panel; η = 21.0%
The insolation of it = 650 W/m².
Hence, input power of the solar panel: I = insolation × area
= 650 × 1.25 W
= 812.5 W.
Output power of the solar panel: O = efficiency × input power
= 21.0% ×821.5 W
= 170.6 W.
Hence, its output power is 170.6 W.

Speed is the time rate at which an object is shifting along a path, even as speed is the fee and route of an item's movement. Positioned every other manner, speed is a scalar value, even as pace is a vector.
Velocity (or price, r) is a scalar quantity that measures the gap traveled (d) over the alternate in time (Δt), represented via the equation r = d/Δt.

A hockey puck with a mass of 0. 12 kg is traveling across the ice at a velocity of 150 m/s downfield. What is the momentum of the hockey puck?.
The momentum of the hockey puck is 18 kgm/s.
Momentum of any object is nothing but the product of mass and velocity. Momentum is a vector quantity so it is having both mass and direction. generally the direction of momentum is the same as the direction of velocity, because mass is a scalar quantity.
It means we can write that,
momentum = mass x velocity
P = mxv
here in the question we have mass 0.12 kg and velocity is 150 m/s, so we can write
P = 0.12 x 150 (kgm/s)
p = 18 kgm/s

A 20 N force accelerates a 5 kg trolley from 2 m/s to 5 m/s. How long does this change of velocity take?
The correct answer is 0.75 second will take to change velocity.
What connection exists between force and mass of acceleration?
Mass times acceleration, or F=m x a, equals force. This means that in order to move an object at the same speed or velocity as an object with smaller mass, a stronger force is required. Newton's Second Law of Motion is this.
Given, Initial velocity u = 2 m/s
Final velocity v=5 m/s, mass of trolley = 5 Kg. , Force = 20 N
Force = Mass x acceleration
20 N = 5 x a

The velocity of sound waves is roughly the same for all wavelengths. Suppose that a sound wave has a wavelength of one meter and a frequency of 1000hz. The wavelength of a 250hz sound wave would then be.
Answer:
4 m
Explanation:
[tex]v = f \times λ[/tex]
speed of sound wave (according to question)
= 1 × 1000 = 1000m/s
wavelength is represented by λ
therefore to find the wavelength, divide the speed by the frequency of the second wave given by the question
λ of another wave = 1000 ÷ 250 = 4 m
Speed of sound equals wavelength and frequency. The wavelength of the sound wave if the frequency is 250hz is 4 meters.
What is the speed of sound waves?
Sound requires a medium to propagate in the form of vibration. It is the pattern of disturbance caused by the movement of energy particles propagating through the medium.
Sound waves can travel in the form of transverse and longitudinal waves. When the sound source continues to vibrate in the medium, the vibrations are propagated in the form of sound waves.
The sound waves travel at different speeds in different mediums. the speed of sound waves remains constant in the same medium. The speed of sound waves is directly proportional to wavelength and frequency.
Wavelength(λ) measures the distance between two crests/ two troughs in a wave and its SI unit is a meter. The frequency (f) of a wave is the number of waves that pass in a certain time and its unit is hertz(Hz). The SI unit of the speed sound wave is m/s.
From the givens,
wavelength(λ) = 1 meter.
frequency (f) = 1000hz.
Speed of wave(v) = wavelength × frequency
= 1 × 1000
v = 1000 m/s.
speed of wave = 1000 m/s.
frequency = 250hz
wavelength(λ) = speed / frequency
= 1000 / 250
= 4 meters.
Hence, the wavelength(λ) of a 250 hz sound wave is 4 meters.

What kind of force is a centripetal force?Centripetal force is the force exerted on an object moving curvilinearly that is pointed in the direction of the object's axis of rotation or center of curvature. Newton is the symbol for centripetal force. Whenever an object moves, the centripetal force is applied perpendicular to that direction.
How is centripetal force generated?Gravity is the centripetal force in Newtonian mechanics that drives astronomical orbits. The scenario in which a body travels at a constant speed along a circular path is a typical illustration of centripetal force.

Karl measures the current through a resistor. What else will he need to measure in order to work out its resistance? give the full name, not the symbol.
Answer:
Explanation:
The voltage across the resistor
then ohms = voltage / current
Conider a particle whir ling about a circular path of radiu 44m with a tangential velocity of magnitude 24m/ find the magnitude of the angular velocity ?
The magnitude of the angular velocity of a particle whirling about a circular path of radius 44m with a tangential velocity of magnitude 24 m / s is 0.55 rad / s
v = r ω
v = Tangential velocity
r = Radius
ω = Angular velocity
r = 44 m
v = 24 m / s
ω = v / r
ω = 24 / 44
ω = 0.55 rad / s
Tangential velocity is also known as linear velocity. So the linear velocity value multiplied by the radius of the curve gives the value of angular velocity which is represented using the unit rad / s.
Therefore, the magnitude of the angular velocity is 0.55 rad / s

How may the stability of a body be increased?
Answer:
The functionality of a body can be restored with the help of appropriate flexibility and strengthening. Once everything is in place, you can exercise those muscles specifically for balance to put them to the test. Your body may then adjust, improving your general stability as you get better at completing those activities.
Answer:
The stability of an object is increased when the lower the centre of gravity is.
So we should try to lower the centre of gravity.
