Forces normal to a particle's displacement do no work.

Physics
1 answer:
snow_tiger [21]3 years ago
3 0

Answer:

Explanation:

The work done is defined as the product of force applied in the direction of displacement and the displacement.

W = F x d x Cosθ

where, F is the force applied, d be the displacement and θ be the angle between the displacement and force.

For the normal forces, the angle between the displacement and the force applied is 90 degree, and the value of Cos 90 is zero, so the work done is zero.

Use the mass and volume data to calculate the density of liquid propane to the nearest hundredth.
Black_prince [1.1K]
Density = mass/volume 
              = 4300/10000
              =    0.43 g/mL.

Therefore density of liquid propane is 0.43 g/mL.

Hope this helps!

¿Qué resistencia debe ser conectada en paralelo con una de 20 Ω para hacer una
ValentinkaMS [17]

Answer:

60 Ω

Explanation:

R(com) = 15 Ω

1/R(com) = 1/R1 + 1/R2 + 1/R3 ..... + 1/Rn

1/15 = 1/20 + 1/R2

1/R2 = 1/15 - 1/20

1/R2 = (4 - 3) / 60

1/R2 = 1/60

R2 = 60 Ω

así, la combinada de resistencia necesaria es 60 Ω

5. Is the following measurement, 9.7 x 104 km East, a vector quantity or a scalar<br> quantity?
Neporo4naja [7]

Answer:

Vector quantity

Explanation:

What is a vector quantity?

-> A vector quantity has both direction and magnitude

What is scalar quantity?

-> S scalar quantity has only magnitude

[] Based on these definitions, 9.7 x 104 km East is a vector quantity because it includes a direction, East.

Have a nice day!
