Answer:

The answer is most likely C.

Ready-to-eat foods are stored at the top of the fridge, away from raw foods so that harmful bacteria cannot transfer from the raw food to the cooked food. Raw meat, poultry and fish in sealed containers to stop them touching or dripping onto other foods.

A 0.140-kg baseball is pitched horizontally at 33.6 m/s. When a player hits the ball, it moves at the
Mars2501 [29]

Answer:

F = 1176 N

Explanation:

Given that,

Mass of a baseball, m = 0.140-kg

Initial speed of the baseball, u = 33.6 m/s

Final speed of the baseball, v = -33.6 m/s (in opposite direction)

The time of contact of the bat and the ball, t = 0.008 s

We need to find the  average force the bat exerts on the ball. The force acting on the ball is given by :

F=ma\\\\F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{0.14(-33.6-33.6)}{0.008}\\F= -1176\ N

So, the average force the bat exerts on the ball is 1176 N.

the angular velocity of a rotating rigid body is -4+j-2k.find the linear velocity if a point p(5,1,3) on the body relative to a
vekshin1

The linear velocity of a point p(5,1,3) on the body relative to a point Q(3,4,2) on the axis of rotation​ is 17.13 m/s.

<h3>What is linear velocity?</h3>

Linear velocity is defined as the rate of change of displacement with respect to time when the object moves along a straight path.

The relationship between linear velocity and angular velocity is given as;

v = ωr

where;

  • ω is angular speed of the object
  • r is the radius of the circular path
  • v is the linear speed of the object

The magnitude of the radius is calculated as follows;

r = √[(5-3)² + (1-4)² + (3-2)²]

r = 3.74 m

The magnitude of the angular speed is calculated as;

ω = √[(-4)² + (1)² + (-2)²]

ω = 4.58 rad/s

The linear speed of the object is calculated as follows;

v = ωr

v = (4.58 rad/s) x (3.74 m)

v = 17.13 m/s

3. the definition of the FREQUENCY of a sound is​
sergiy2304 [10]
Definition: Frequency is the measurement of the number of times that a repeated event occurs per unit of time. Sound moves through a medium such as air or water as waves. It is measured in terms of frequency and amplitude. Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself.
