-- Mass can be measured using a balance.
(It's not the only way.)

-- The mass of an object remains constant,
no matter where it is or what it weighs.

-- The "kilogram" is the international standard unit of mass.
A kilogram of mass weighs about 5.8 ounces on the moon,
about 13.3 ounces on Mars, about 2.2 pounds on Earth . . . . .

An object that is in free fall seems to be ______
bekas [8.4K]


An object that is in free fall seems to be (D) weightless.

Objects which are in free fall are said to be weightless because they only have the force of gravity acting upon them. Objects in free fall do not experience air resistance.

A ball is projected at an immovable wall with a speed vi and bounces back the wall in such a manner that it only has 1/3 of its
sergey [27]

The fraction of the kinetic energy of the ball lost during the collision is \frac{1}{3}.

The given parameters;

  • <em>initial speed of the ball, = vi</em>
  • <em>final momentum of the ball, Pf = ¹/₃Pi</em>

The initial and final momentum of the ball is calculated as;

P_i = m_ivi

P_f = m_fv_f = \frac{1}{3} m_iv_i

The initial and final kinetic energy of the ball is calculated as;

K.E_i = \frac{1}{2} m_iv_i^2 = \frac{1}{2} P_iv_i\\\\K.E_f = \frac{1}{2} m_fv_f^2= \frac{1}{2} (\frac{1}{3} P_iv_i)= \frac{1}{6} P_iv_i

The change in the kinetic energy is calculated as;

\Delta K.E = K.E_f - K.E_i \\\\\Delta K.E = \frac{1}{6} P_iv_i - \frac{1}{2} P_iv_i = \frac{1}{3} P_iv_i

Thus, the fraction of the kinetic energy of the ball lost during the collision is \frac{1}{3}.

Two vectors, A and B, have magnitudes of 10 and 15. The cross product of these vectors has magnitude 32. What is the angle betwe
zalisa [80]

Answer:

The Angle between the vector A and B is 12.32°

Explanation:

Given data

|A×B|=32

|A|=10

|B|=15

To find

Angle α

Solution

From Cross product properties we know that

|A*B|=|A||B|Sin\alpha \\32=(10)(15)Sin\alpha\\Sin\alpha=32/150\\\alpha =Sin^{-1}(32/150)\\\alpha  =12.32^{o}

The Angle between the vector A and B is 12.32°
