Which statement is true regarding the relationship between distance and displacement

2 answers:

7 0

Distance is a scalar and equals to the total distance travelled.
Displacement is a vector and equals to the change in position. Final position - Initial position. The relationship between distance and displacement is that it is motion. The object is in motion and changes his position over time.

Distance is always either the same or greater than the displacement for the same trip. Distance can never be less than displacement.

You haven't listed any choices so it's not possible to help you choose the correct one.

For a ∆x of 0.1mm, what is ∆px, the uncertainty in the transverse momentum of a photon passing through a slit (where uncertainty

Colt1911 [192]

Answer:

$0.53\times 10^{-30}kgms^{-1}$

Explanation:

Uncertainty principle say that the position and momentum can not be measured simultaneously except one relation which is described below,

$\Delta x\Delta p=\frac{h}{4\pi }$

Given that the uncertainty in x is 0.1 mm.

Therefore,

$\Delta p=\frac{6.626\times 10^{-34} }{4\times 3.14\times 1\times 10^{-4}m }\\\Delta p=0.53\times 10^{-30}kgms^{-1}$

Therefore, uncertainty in the transverse momentum of photon is $0.53\times 10^{-30}kgms^{-1}$

A 20 kg bike accelerates at 10 m/s2. What was the force?

agasfer [191]

Answer:

200 N = 200 Newtons

Explanation:

Just use the formula F = m*a

F = Force in Newtons

m = mass and is 20 kg

a = acceleration and is 10 m/s^2

F = 20 * 10

F = 200 Newtons.
