Sally and ann are trying to move a box across the floor. Sally is pushing the box to the right with a force of 100n and ann is pulling the box with a force of 50n to the right. What is the magnitude and direction of the box?.

Answers

Answer:

150N to the right...

Explanation:Force acting on the box applied by Sally,  F1= 100 N (right side)

Force acting on the box applied by Ann,  F2= 50 N (right side)

It is clear that the two forces are acting on same direction. Let right side is positive direction. So, F= F1 + F2

                                      F= 100+50

                                       F=150 N

 The direction of the box is towards the right side. So, the correct option is 150 N to the right... Hope this helps... Plz mark me brainliest.... Stay safe and have a great weekend!!! :D

A 400-kg box is lifted vertically upward with constant velocity by means of two cables pulling at 40. 0° on either side of the vertical direction. What is the tension in each cable?.

Answers

Answer:

2558 N.

Explanation:Each rope takes half, so the vertical component of the force on each rope is half of this, or 1960 N.. But they are pulling at a 40 degree angle, so if t is the tension then t*cos(40) = 1960. This gives t = 2558 N.

When you float an ice cube in water, you notice that 90% of it is submerged beneath the surface. Now suppose you put the same ice cube in a glass of some liquid whose density is less than that of water.

Answers

Answer:

option c

Explanation:

90% of the body is submerged in water.

Now it is immersed in an unknown liquid whose density is less than the density of water.

Buoyant force acting on the body depends on the volume immersed, density of liquid and gravity.

As the density of liquid is less than the density of water, so the buoyant force acting on the body by the unknown liquid is less than water. So it is submerged less than 90% in this liquid.

Two facts that I learned during my research were narrowing down the research topic and setting appropriate goals.

When doing research, several aspects must be taken into account so that the research has good results and produces new knowledge. Here are two tips for proper research:

1. Limit the subject of the investigation: When conducting an investigation it is necessary to limit the subject so that it is easier to achieve an effective result. For example, time limits, a specific place, and more special aspects should be set to make the investigation more specialized.

Which situation describes an object that has no unbalanced force acting on it.

Answers

The situation which best describes an object that has no unbalanced force acting on it is: A hockey puck moving at constant velocity across ice.

A force can be defined as a push or pull of objects, which typically results in a change of motion due to the interaction of the object with another.

In Science (Physics), there are two (2) main types of force and these are:

Balanced force.Unbalanced force.

An unbalanced force is a type of force that occurs when two or more forces acting on an object are unequal in magnitude and as such, it typically results in a change of motion.

Hence, a hockey puck that is moving at a constant velocity across ice has no unbalanced force acting on it because it won't experience a change of motion.
