The amount of energy required to increase the temperature of 20 g of water from 283°C to 303°C is approximately 6.1 kJ.
How much energy must be absorbed by 20 point grams of water to increase its temperature from 283 degrees Celsius to 303°C?To calculate the amount of energy absorbed by 20g of water when its temperature increases from 283°C to 303°C, you must use the formula for specific heat capacity.Specific heat capacity is the amount of energy required to raise the temperature of 1g of a substance by 1°C. The formula for specific heat capacity is Q=mcΔT, where Q is the energy absorbed, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. In this case, the mass of the water is 20g, the change in temperature is 20°C, and the specific heat capacity of water is 4.2 J/g°C. Therefore, the energy required to increase the temperature of 20g of water from 283°C to 303°C can be calculated as follows: Q= 20g x 4.2 J/g°C x 20°C = 1680J. Therefore, the amount of energy absorbed by 20g of water to increase its temperature from 283°C to 303°C is 1680J.

consider two bodies A and B of masses m1 and m2 moving along the same straight line in the same direction with velocities u1 and u2. the bodies A and B suffer a head on collision when they strike and continue to move along the same straight line of velocities v1 and v2 respectively. Assume the collision is elastic , show that u1 + v1 = u2 + v2
As the collision is elastic, u₁ + u₂ = v₁ + v₂ must be satisfied.
What is law of momentum conservation?According to the law of momentum conservation, momentum is never created nor destroyed inside a problem domain.
Before collision,
velocity of body A = u₁ velocity of body B = u₂
After collision,
velocity of body A = v₁ velocity of body B = v₂
Hence, according to law of momentum conservation
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
As the collision is elastic, total kinetic energy is also conserved.

In your opinion, how do you think to go faster than the speed of light?
Answer:
According to special relativity, nothing can travel faster than the speed of light – an object with mass would require more energy to accelerate closer to the speed of light without actually reaching it.
Explanation:
Hope this helps!
Hypothetically somthing can match if not exceed the speed of light based on our perspective. I'll use Hubble's law for example (the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance). To us there are some galaxies so far away from us that they appear or should logically be moving away from us at the speed of light or greater. However the galaxies are not actually moving but rather the space in-between galaxies are expanding indefinitely. But because of our perspective it appers that the galaxies are going through space at unthinkable speeds.

a. the initial velocity u,
b. the height h,
c. the maximum height H reached by the ball.
The initial velocity u be the product of time t and acceleration due to gravity g thus u = gt. Then height that the ball can move with this velocity is 1/2 gt².
What is velocity ?Velocity of a moving object is the measure of its distance travelled per unit time. Velocity is a vector quantity having both magnitude and direction. Acceleration is the rate of change in velocity.
Here, the initial velocity is given u. It is the product of acceleration g and time t. thus, u = gt.
The height travelled within the time t and acceleration g, is written as:
h = 1/2 gt²
Now, when the ball reaches its maximum height, its potential energy becomes equal to the kinetic energy.

A fishing boat uses an ultrasound of frequency 4.0×10²Hz to detect a fish blow it. two echo's of the ultrasound are received after 0.09s coming from the shoal of the fish and the other after 0.12s coming from the sea bed .if the sea bed is 64m below the ultrasound transmitter and the receiver, calculate; a. the speed of the ultrasound in water b. the wavelength of ultrasound in water. c. the depth of the fish below the boat.
a. the speed of the ultrasound in water is 1480 m/s
b. the wavelength of the ultrasound in water is 37 m
c. the depth of the fish below the boat is 89.76 m
How to calculate?a.
v = fλ
v = fλ = (4.0 x 10^2 Hz)(λ)
the speed of the ultrasound in water is given as :
v = v_water = 1480 m/s
substitute v_water into the equation above and solve for λ:
λ = v_water / f = (1480 m/s) / (4.0 x 10^2 Hz) = 37 m
Therefore, the speed of the ultrasound in water is 1480 m/s and the wavelength is 37 m.
c. The depth of the fish below the boat ia found using,
d = v_water * t / 2
The first echo came back after 0.09 s:
d = (1480 m/s) * (0.09 s) / 2 = 64.32 m
This is the depth of the sea bed, which is already known to be 64 m. So the fish must be deeper than the sea bed, and the second echo must have come from the fish. The second echo came back after 0.12 s:

The normal stress is 1292.5 Pa and the shear stress is 330 Pa on the plane at an angle of 50° relative to the principal stress axes.
What is shear stress?Shear stress is described as the component of stress coplanar with a material cross section which arises from the shear force, the component of force vector parallel to the material cross section.
We will calculate the major and minor principal stresses:
σ1 = (ob + ja) / 2 + (ja - ob) / 2 * cos(2b)
σ2 = (ob + ja) / 2 - (ja - ob) / 2 * cos(2b)
The normal stress on the plane at angle b can be calculated as:
σ = (σ1 + σ2) / 2 + (σ1 - σ2) / 2 * cos(2b)
The shear stress on the plane at angle b can be calculated as:
τ = (σ1 - σ2) / 2 * sin(2b)
Applying the formulas, we have:
σ1 = (500 + 1500) / 2 + (1500 - 500) / 2 * cos(2 * 50) = 1000 + 500 * 0.87 = 1000 + 435 = 1435 Pa
σ2 = (500 + 1500) / 2 - (1500 - 500) / 2 * cos(2 * 50) = 1000 - 500 * 0.87 = 1000 - 435 = 565 Pa
σ = (1435 + 565) / 2 + (1435 - 565) / 2 * cos(2 * 50) = 1000 + 435 * cos(100) = 1000 + 292.5 = 1292.5 Pa
τ = (1435 - 565) / 2 * sin(2 * 50) = 435 * sin(100) = 435 * 0.76 = 330 Pa

Calculate the distance in m between two adjacent nodes
The fourth harmonic of B matches the frequency of A 's first harmonic, and the distance is ¼fn.
What is frequency?
The number of waves that pass through a fixed point in a given amount of time is defined as frequency. If a wave takes 1/2 second to pass, the frequency is 2 per second. If it takes one hundredth of an hour, the frequency is one hundred per hour.
The hertz unit, named after the 19th-century German physicist Heinrich Rudolf Hertz, is typically used to measure frequency. The hertz measurement, abbreviated Hz, is the number of waves per second that pass by. An "A" note on a violin string, for example, vibrates at about 440 Hz (440 vibrations per second).
The n th resonant frequency of string A is
fn,A
= vA/2IA× n
= n/2L √τ/μ
while for string B it is
fn,B
= vB/2IB × n

Do sound waves travel faster through solids or gases? I WILL GIVE Brainliset.
Answer:
Sound waves travel faster through solids than through gases.
Explanation:
The speed of sound in a solid is determined by its elasticity and density. Solids are generally denser and more elastic than gases, so they can transfer the energy of a sound wave more effectively, leading to a faster speed of sound.
The speed of sound in a gas is influenced by its temperature, pressure, and composition. Gases are generally less dense and less elastic than solids, so they transfer the energy of a sound wave less effectively, leading to a slower speed of sound.
In general, the speed of sound in solids is about four to five times faster than in gases.
Answer: Solids.
Explanation: Because gas have molecules too far a part, the sound has issues traveling through it. On the other hand solids have the molecules very close together so the sound waves travel more quickly through it.
Sound waves travel over 17 times faster through steel than through air.
Basically, the more close together the molecules are, the faster the sound will spread.

For the elastic collision, the momentum remains conserved. So -
