Explain which has a greater inertia - a speeding car or jet plane sitting on a runway?

Answers

Answer 1

Answer:

Explanation:

Inertia is related to only mass, not speed.

Since a jet plane has more mass than a car, it has more inertia.

A bicyclist is in a 50-km race. He says he had an average velocity of 35. What is missing in the cyclist’s velocity? A. units only B. units and distance C. direction only D. units and direction

Answers

Answer: (D). The unit and direction is missing.

Explanation:

Velocity: Velocity is the speed of the object with direction and it is the vector quantity. The unit of velocity is m/s.

Average velocity: Average velocity is defined as the total distance divided by the total time.

$\Delta v=(D)/(T)$

Here,

D = Total distance

T = Total time

According to the question:

The unit and the direction is missing in the cyclist's velocity.

Hence, The unit and direction is missing.

ACTUALLY... The answer is units and direction.

Answers

Answer: 38.25 m

Explanation:

In this situation we need to find the distance $d$ between the rabbit and the carrot, and we can use the following equation, since the rabbit's acceleration is constant:

$V^(2)=V_(o)^(2) + 2ad$ (1)

Where:

$V=13 m/s$ is the rabbit's maximum velocity (final velocity)

$V_(o)=4 m/s$ is the rabbit's initial velocity

$a=2 m/s^(2)$ is the rabbit's acceleration

$d$ is the distance between the rabbit and the carrot

Isolating $d$ :

$d=(V^(2)-V_(o)^(2))/(2a)$ (2)

$d=((13 m/s)^(2)-(4 m/s)^(2))/(2(2 m/s^(2)))$ (3)

Finally:

$d=38.25 m$

A student want to see what floats better a 1 pound piece of wood with a density of 0.90g/ml or a 10 pound piece of wood with a density 0.90g/ml explain your reasoning

Answers

The buoyancy of an object depends on its density relative to the density of the fluid it's placed in, typically water in everyday scenarios. When an object is placed in a fluid (like water), it will float if its average density is less than that of the fluid. In other words, if the object is less dense than the fluid, it will float.

In this case, both pieces of wood have the same density of 0.90 grams per milliliter (g/ml), which is less dense than water. Therefore, both the 1-pound piece of wood and the 10-pound piece of wood will float in water.

However, it's important to note that the buoyant force acting on these objects will be the same for a given volume of wood because they have the same density.

The 10-pound piece of wood will displace more water (have a larger volume) to support its weight, while the 1-pound piece of wood will displace less water (have a smaller volume) to support its weight. The 10-pound piece of wood will have more of its volume submerged compared to the 1-pound piece due to the weight difference, but both will float.
