Answer:
24cm from the surface
Explanation:
Equation for refraction
n2/v- n1/u = n2-n1/R
= u = infinity ( parallel)
2/v= (2-1)/R
V = 2R
V= 24cm
Answer:
The temperature rise is given as 21.35 K
Explanation:
The explanation is shown on the first second and third uploaded image
Answer:
a = 0.55 m/s/s
Explanation:
As the car accelerates in forward direction the string will make some angle with the vertical direction
So here horizontal component of the tension force will accelerates the dice in forward direction along with the car
Vertical component of the tension force will balance the weight of the dice
so we will have
here we know that
= angle made with the vertical by string
now divide the two equations
so we have
Answer:
The diameter of the piston of the players equals 55.136 cm.
Explanation:
from the principle of transmission of pressure in a hydraulic lift we have
Since the force in the question is the weight of the individuals thus upon putting the values in the above equation we get
Solving for we get
