Ben is pushing a small trolley 10 N to the north and but Gary is pushing the trolley 5 N to the south. What is the total applied
andrew-mc [135]

Answer:

The total applied force on the trolley is 5 N toward the North.

Explanation:

In this problem, Ben is pushing the trolley to north and Gary is pushing it to south. So both the forces are acting 180° opposite to each other. As force is a vector quantity, the net force or total force acting on any object should be calculated by vector addition of number of forces along with their directions. So in this case, if we consider the force Ben is applying as F1 and the force Gary is applying as F2 on the trolley. Then the net or total force acting on the trolley will be F1-F2. This is because, F1 and F2 are acting opposite to each other in direction.Thus, Total force acting on the trolley = 10 N - 5 N.

So the total force acting on the trolley is 5 N and it is toward the north direction.

Number of atoms in 5.40gB
Stolb23 [73]
First, take the molar mass of B (10.81g) and divide the value you've been given by the molar mass to get moles (5.4 / 10.81). So you have .5 moles of B and then you need to convert that to atoms. To do that you must use the constant 6.022X10^23 atoms per mole. Take your moles and multiply it by that constant. Your final answer should be (3.01X10^23) atoms.

Hope this helps!

What is the frequency of a 4,600 cm wave?
ddd [48]

The frequency of a 4,600 cm wave is 652 Hz

Frequency is the number of waves that pass a fixed point in unit time

Here given data is

Wave =  4,600 cm = 4.6 × 10⁸ nm

We have to calculated frequency = ?

Frequency =v = c/λ

Frequency = 3×10⁸m / 4.6 × 10⁸ nm

Frequency = 652 Hz
