A heavy rocket ship and a light rocket ship are both initially moving at 1000 kilometers per hour in outer space. They are very
cestrela7 [59]

Answer:Both will continue traveling at the same speed because there is no friction.

Explanation: Gravitational force or pull is the force acting to attract all object in and around the Earth to the center of the Earth. The Earth's Gravitational force acts as a Bar magnet.

When objects are working outside the impact of the force of Gravity,it will not matter whether the objects are of the same size or wether one is heavier than the other,in this case both objects will move at the same speed as there is no impact of the Force of Gravity.

g During the contraction of the heart, 65 cm3 blood is ejected from the left ventricle into the aorta with a velocity of approxi
Alisiya [41]

Answer:

The force is F = 0.1441 \  N

Explanation:

From the question we are told that

   The volume of blood ejected is  V_b  =  65cm^3 = 65*10^{-6} \  m^3

    The velocity of the ejected blood is  v  = 98 cm/ s = 0.98 \  m/s

    The mass density of blood is  \rho = 1060 \  kg/m^3

    The heart rate is  R  =  61 bpm(beats \  per \  miunite) = \frac{61}{60} = 1.0667\  bps

Generally the average force exerted is mathematically represented as

     F = 2 *  \rho *  V_b *  R *  v

=>   F = 2 * 1060  *  (65*10^{-6}) *1.0667   *   0.98

=>   F = 0.1441 \  N

A 0.017-kg acorn falls from a position in an oak tree that is 18.5 meters above the ground.
Marianna [84]

Answer:

Part a)

Final speed of the corn is 19.05 m/s

Part b)

Kinetic energy of the corn is 3.1 J

Explanation:

Part a)

As we know that the initial position of the corn is

h = 18.5 m

now we also know that it will fall from rest and moving under constant acceleration so we will have

v_f^2 - v_i^2 = 2 a d

v_f^2 - 0 = 2(9.81)(18.5)

v_f = 19.05 m/s

Part b)

Kinetic energy of the corn is given as

K = \frac{1}{2}mv^2

K = \frac{1}{2}(0.017)(19.05)^2

K = 3.1 J
