Superkid, finally fed up with Superbully's obnoxious behaviour, hurls a 1.35 kg stone at him at 0.501 of the speed of light. How much kinetic energy do Superkid's super arm muscles give the stone
Answer:
See below
Explanation:
A lot !
KE = 1/2 m v^2
= 1/2 * 1.35 * ( .501 * 3 * 10^8)^2 =
1.5248 x 10^16 j
kinetic energy do Superkid's super arm muscles give the stone is 62.6 × 10⁶ J.
What is kinetic energy ?Kinetic energy is the energy associated with a motion of a body. When a body is in motion having mass m then it has kinetic energy. Kinetic energy is denoted by K or T. it is expressed in joules. Kinetic energy is given by,
K = 1/2 mv²
Hence an object having zero mass or zero velocity have zero kinetic energy.
In this problem the stone is moving with velocity which is comparable with the speed of light, hence we have to find relativistic kinetic energy.
The relativistic kinetic energy is given by,
[tex]K = m_{0} c^2(\frac{1}{\sqrt{1-\frac{v^2}{c^2}} } -1)[/tex]
putting all the values in the equation
[tex]K = 1.35*3*10^8(\frac{1}{\sqrt{1-\frac{(0.5c)^2}{c^2} } }-1 )[/tex]
K = 62.6 × 10⁶ J

Answer:
When oil is spilled in the sea it will normally break up and be dissipated or scattered into the marine environment over time. This dissipation is a result of a number of chemical and physical processes that change the compounds that make up oil when it is spilled. The processes are collectively known as weathering.

An inductor produces a back emf in a dc series rl circuit when a switch connecting the battery to the circuit is closed. We can explain this by.
Hi there!
Let's say that a series RL circuit is constructed, with the switch left open.
When the switch is closed, a current will start flowing in the circuit. The INCREASING current will go through the loops of the inductor, producing an INCREASING magnetic field and consequentially a magnetic flux through the inductor. (Use hand rules).
However, the inductor does NOT want to experience this increasing magnetic flux, so an emf in the OPPOSITE direction of the current will be produced to counteract the increasing flux. (The flux would also be in the opposite direction).
This is expressed with the equation:
[tex]\epsilon = -L \frac{di}{dt}[/tex]
ε = Back emf (V)
L = Inductance (H)
i = Current (A)
t = time (s)
With the negative sign, we can see that if the current of the circuit is INCREASING, the emf produced would be in the opposite direction.

The acceleration, a of the bodies given is the change in velocity with time and is given as follows:
a = 1.2 m/sa = 25 km/hra = 35.3 cm/mina = 7.125 km/mina = 1.69 m/sa = 108.1 m/hra = -1.0 cm/sa = 7.89 km/hra = 1.17 ft/sa = 3.13 km/hrWhat is acceleration?Acceleration is the rate of changeof velocity of an object with time.
Acceleration, a = change in velocity/time takenFor the given questions, the acceleration are as follow:
a = (40 - 10)/25 = 1.2 m/sa = (75 - 30)/1.8 = 25 km/hra = (90 - 60)/0.85 = 35.3 cm/mina = (77 - 20)/8 = 7.125 km/mina = (37 - 15)/13 = 1.69 m/sa = (40 - 0)/0.37 = 108.1 m/hra = (13 - 25)/12 = -1.0 cm/sa = (48 - 18)/3.8 = 7.89 km/hra = (52 - 38)/12 = 1.17 ft/sa = (43 - 17)/8.3 = 3.13 km/hrTherefore, the acceleration of a body is either positive or negative.

A monochromatic light passes through a narrow slit and forms a diffraction pattern on a screen behind the slit. As the slit width increases, the diffraction pattern:.
As the slit width increases, the diffraction pattern gets narrower and vice versa.
Relationship between width and diffraction patternThe increase in silt width leads to the narrowing of diffraction pattern of the light because the increase of width reduces the space for the passing of light wave.
