The density of an object is dependent of an object?

Answers

Answer 1

Answer: Hey there!

Answer: Mass and Volume

The density of an object is dependent of an object's mass and volume. To calculate an object's density, simply divide it's mass by it's volume.

A 10 kg bear is running to the right at 10 m/s. He crashes into another 10 kg bear running to the left at -5 m/s. They collide and stick together, and move on together at 2.5 m/s. Write at least 2 or 3 sentences explaining whether momentum was conserved in this situation.

Answers

Answer:

Total momentum is conserved

Explanation:

Conservation of Momentum

The momentum is a physical magnitude that measures the product of the object's velocity by its mass. The total momentum of a system is the sum of all its components' individual momentums. The two-bear system starts with a total moment of

$p=m_1v_1+m_2v_2=(10)(10)+(10)(-50)=50\ kg.m/s$

When both bears stick together, the total mass is 20 kg, and the new momentum is

$p'=(20)(2.5)=50 \ kg.m/s$

We have assumed both bears move to the right after the collision. In this situation, the total momentum is conserved

3. The smallest bird is the Cuban bee hummingbird, which has a mass of only1.7 g. If this bird did 8.8 x 10-4 J of work by exerting an upward force of
3.4 x 10-N, how far did it fly?

Answers

Answer:

2.6 m

Explanation:

The work done by the bird is given by

$W=Fd$

where

F is the force exerted

d is the distance covered

In this problem, we know:

$W=8.8\cdot 10^(-4) J$ is the work

$F=3.4\cdot 10^(-4) N$ is the force

Solving the equation for d, we find the distance covered by the bird:

$d=(W)/(F)=(8.8\cdot 10^(-4))/(3.4\cdot 10^(-4))=2.6 m$

Final answer:

The Cuban bee hummingbird flew approximately 2.59 x 10^-2 meters.

Explanation:

To determine the distance the bird flew, we can use the equation: work = force x distance. Rearranging the equation, distance = work / force. Plugging in the values, we have distance = (8.8 x 10-4 J) / (3.4 x 10-2 N). Solving this equation gives us a distance of approximately 2.59 x 10-2 meters.
