Answer:
F= 134.92 N
Explanation:
Given that
The mass of the moon ,M = 7.4 x 10²² kg
The mass of the man ,m = 79 kg
The radius ,R= 1.7 x 10⁶ m
The force exerted by moon is given as
Now by putting the values in the above equation we get
Therefore the force will be 134.92 N.
F= 134.92 N
Answer:
5.14 J
Explanation:
l = 81 cm = 0.81 m
diameter = 3 mm
Radius, r = 1.5 mm = 1.5 x 10^-3 m
Change in temperature, T2 - T1 = 50 degree
t = 1.8 minutes = 1.8 x 60 = 108 s
k = 109 W/mk
Heat transfer = K A (T2 - T1) t / l
H = 109 x 3.14 x 1.5 x 10^-3 x 1.5 x 10^-3 x 50 x 108 / 0.81
H = 5.14 J
Answer:
Explanation:
One of the consecuences of Special Theory of Relativity is that when bodies move its length in the direction of the movement will decrease, and decrease will become bigger as speed goes up. At speed close to speed of light such decrease could be such as to make train become a point, of course tunnel is fixed it will not change, but close to light speed means somethyng like 300000 km/sec therefore could be just one instant of time inside tunnel no matter how long it is
Answer:
Well, acceleration is the rate of change of velocity of an object with respect to time
The mass of the first block will be three times the mass of the second block.
According to Newton's second law of motion, the force acting on a body is directly proportional to the acceleration as shown;
F is the acting force
m is the mass
a is the acceleration of the body
Given the following parameters
Constant force F = 1N
For the first block with the acceleration of "a"
1 = m₁a
a = m₁/1
m₁ = a .................1
For the second block, acceleration is thrice that of the first. This means;
F = m(3a)
1 = 3ma
..........................2
Divide both equations
From the calculation, we can conclude that the mass of the first block will be three times the mass of the second block.
