Answer:
Characteristics passed down from parent to offspring.
Explanation:
Inherited traits are given to the offspring from the parents.
"Characteristics are passed down from the offspring to the parent" does not make sense.
"The offspring of a plant" and "The parent of an offspring" are wrong.
Answer:
It depends on the mass of each of the bodies, and the distance that separates them.
Explanation:
The force of attraction between two objects depends on the mass of each of the bodies as well as the distance that separates them. This force can be easily calculated by means of the universal gravitation law formulated by Newton.
Next, we will see the equation that explains the law of universal gravitation.
Answer:
Force is measured in "Newton's" - kg-m/s^2
F = M a = kg * m/s^2
This in the kgm-m systen - in the gram-cm system you have
F = dynes = gram-cm/s^2
Since 1 gm = .001 kg and 1 cm = .01 m
1 dyne = 1.0^-5 newtons
Answer:
33.33j+6.67i km/hr
Explanation:
From the law of conservation of momentum,
Applying,
mu+m'u' = V(m+m')............... Equation 1
Where m = mass of the truck, m' = mass of the car, u = initial velocity of the truck, u' = initial velocity of the car, V = Final velocity.
Note: let j represent the north, and i represent the east
From the question,
Given: m = 1500 kg, u = 60j, m' = 1200 kg, u' = 15i
Substitute these values into equation 1
1500*60j+1200*15i = V(1500+1200)
90000j+18000i = 2700V
V = (90000j+18000i)/2700
V = 33.33j+6.67i km/hr
Complete Question
A light spring with force constant 3.05 N/m is compressed by 7.80 cm as it is held between a 0.400-kg block on the left and a 0.800-kg block on the right, both resting on a horizontal surface. The spring exerts a force on each block, tending to push the blocks apart. The blocks are simultaneously released from rest. Find the acceleration with which each block starts to move, given that the coefficient of kinetic friction between each block and the surface is 0, 0.035, and 0.397. (Let the coordinate system be positive to the right and negative to the left. Indicate the direction with the sign of your answer. Assume that the coefficient of static friction is the same as the coefficient of kinetic friction. If the block does not move, enter 0.)
(a) u = 0 heavier block m/s2 m/s2 lighter block
(b)M = 0.035 heavier block m/s2 m/s2 lighter block
Answer:
