When calculated energy transferred between objects use the definition of heat as
Answer:
3.21
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Frequency = 93.5 MHz =
Thus, Wavelength is:
<u>Answer - A.</u>
Explanation:
kinetic potential impulse and velocity
Answer:
2y
Explanation:
Electric field in terms of Electric potential is given as:
E = dV/dr(x, y, z)
Where r(x, y, z) = position in x, y, z plane
The y component of the Electric field will be:
Ey = -dV/dy
Given that
V = 2x - y² - cos(z)
dV/dy = -2y
=> E = - (-2y)
E = 2y
Assume orange is going from left to right and apple is going from right to left
If mv is the momentum of apple at angle θ to the x axis,
In the x direction
0.130*v cos θ = (0.170*1.23) -(0.130*1.08)
0.130*v cos θ = 0.0687-------------------------2
In the y direction
0.130*v sin θ = (0.170*0.974) = 0.16558--------------1
From 1 and 2
tan θ = 2.41
θ = 74.96º
Substituting the value of θ in
0.130*v cos θ = 0.0687
v = 1.38 m/s
