Answer:
Conduction occurs when two objects at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. ... It is caused by the increased activity or speed of molecules in a substance, which in turn causes temperature to rise accordingly. This process continues until heat energy from the warmer object spreads throughout the cooler object.
Explanation:
Answer:
The value is
Explanation:
From the question we are told that
The height is h = 2.0 m
The height of the window is
The initial velocity of the rock is
The angle at which it is thrown is
Generally the vertical component of the velocity of the stone is mathematically represented as
=>
Generally the height of the window from the ground is mathematically represented as using kinematic equation as
=>
Here g is negative -9.8 m/s^2 because the direction of the stone is against gravity
So
Solving this quadratic equation using quadratic formula we obtain
t = 0.770 s
Generally the velocity of the stone on the x axis is mathematically represented as
=>
Generally the distance between the person throwing the rock and the window is mathematically represented as
=>
=>
The end or finish of an event or process.
Answer:
The maximum electric field strength is
Explanation:
Substitute 4.0 cm for D
r = D / 2
r = 4 / 2 = 2cm
= 2 × 10⁻²m
Now, according to the question, the expression for the magnetic field is as follows:
B = 10T + 2T sin(2π(10Hz) t )
Now, calculate
Therefore, the electric field expression is as follows:
Substitute 0 for t in the above equation
Now substitute 1.5 cm for r in the above equation
The maximum electric field strength is
