1. a 3 kg lunch box is pushed across the lunch table. the acceleration of the lunch box is 2.0 m/s2. what was the net force applied to the lunch box? 2. find the weight of a 10 kg rock. remember, acceleration due to gravity is -9.8 m/s2. show your work.

(1)

6 Newtons

Explanation:

The net force is (mass) x (acceleration) = (3 kg) x (2.0 m/s^2) = 6 N

(2)

-98 Newtons

Explanation:

Weight (force due to gravity) is (mass) x (gravitational acceleration) = (10 kg) x (- 9.8 m/s^2) = -98 N

The negative sign due to negative acceleration indicates the gravitational force pointing in the negative direction within the defined coordinate system.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
