Answer:
It actually depends.
Explanation:
in the case of a metal ur hand will absorb the heat (but it depends on the temperature, this ans favours hot and cold but not neutral or room temperature), in the case of human to human I think no heat transfer will take place, in the case of liquids(for hot temperature ,it would even for cold but not room).
It basically involves application
<em>Answer</em><em>:</em><em> </em> The complementary relationship indicated by the Newton's second law...
For a given applied force the acceleration of the trolley is inversely proportional to it's mass.
Answer:
40 N
Explanation:
The gravitational force between the asteroid and the spaceship is given by:
where
is the gravitational constant
is the mass of the asteroid
is the mass of the spaceship
is the distance between the asteroid and the spaceship
The initial force is equal to:
Later, the spaceship moves to a position 3 times as far from the center of the asteroid, so R' = 3R. Therefore, the new force will be
so, the force is decreased by a factor 9. Since the initial force was F=360 N, the new force will be
Answer:
We know that potential energy of a body;
= mass(m)× gravitational acceleration(g) × height(h)
Lets find out the mass of the body
P.E. = mgh
=> 6500J = mass × 9.8m/s^2 × 12m
=>6500J = mass × ( 9.8 × 12 ) × ( m/s^2 × m)
=> 6500 Nm = m × 117.6 × m^2 / s^2
=> 6500/117.6 Ns^2/m = mass [°.° Ns^2/m = kg]
=> 55.272 Kg = mass
Therefore the mass of the body = 55.272 kg ~ <em>6</em><em>0</em><em> </em><em>k</em><em>g</em><em> </em>(Ans)
Hope it helps you
P=m x v =60 x 7.0= 420
total momentum = 420 x 2,000,000,000=dnt have a calculator
thier effect would shake the earth and kill some organism because they jump up at the same time and they wil probably land the same time .
