Answer:

132 g

Explanation:

we know,

moler mass of co₂ = 44.01 g/mol

it means,

1 moles of co₂ =44.01 g

so,

3 moles of co₂ =(44.01 x 3) g

                          =132.03 g

                           ≈ 132 g

A musician hits a drum with a drumstick. In three to four sentences, explain the collision forces between the drum and drumstick
Gnoma [55]

Answer:

Explanation:

In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. When you hit a drum with a drumstick, there is a collision. The force both objects release causes the drumstick to bounce on the drum

Robb wants to win the next sled race. He asks for your advice. What would you tell him he should change in order to win? Explain
In-s [12.5K]

Answer: Start at the top of the hill.

Explanation:

The options include:

a. Start at the bottom of the hill.

b. Start at the top of the hill.

c. Start in the middle of the hill.

Sled racing is simply a winter dog sport racing. Since Robb wants to win the next sled race, the advice that'll be given to him is that he should start at the top of the hill.

Other options such as starting at the bottom of the hill or the middle of the hill are wrong.

Vector c has a magnitude 24.6 m and is in the direction of the negative y-axis. vectors a and b are at angles α = 41.4° and β
storchak [24]
The vector c has a magnitude of 24.6m and it is in the negative y direction. Therefore
\vec{c} = - 24.6 \hat{j}

The vector b is 41.4° up from the x-axis. Therefore
\vec{b} = b[cos(41.4^{o}) \hat{i} + sin(41.4^{o}) \hat{j} ] =b(0.75\hat{i} + 0.6613 \hat{j})

The vector a is 27.7° up from the x-axis. Therefore
\vec{a} = a[cos(22.7^{o})\hat{i} + sin(27.7^{o})\hat{j}] =  a(0.8854\hat{i} + 0.4648\hat{j})

Because \vec{a} +\vec{b} + \vec{c} = 0, the sum of the x and y components should be zero. Therefore,
For the x-component,
0.8854a + 0.75b = 0
 or
 a + 0.847b = 0                            (1)
For the y-component,
0.4648a + 0.6613b - 24.6 = 0
 or
 a + 1.4228b = 52.926                (2)

Subtract (1) from (2).
0.5758b = 52.926
b = 91.917
a = -0.847b = -77.854

Answer:
The magnitude of vector a is -77.85 m
The magnitude of vector b is 91.92 m

Please help what is the definition ligthspeed
aev [14]

Light speed is the speed at which light can travel in a "vacuum" (space for example).

The speed of light is constant and is exactly: 299,792,458 meters per second

ONLY IN A VACUUM!!

The speed of light changes when it goes through different mediums (such as from space to Earth, light travels slower in Earth).

Good luck!
