F = ma,    where m = mass in kg, a = acceleration in m/s², F = Force in Newton

F = 1 * 2

F = 2 N

Force needed is 2 Newtons.

When a potential difference of 154 V is applied to the plates of a parallel-plate capacitor, the plates carry a surface charge d
tester [92]

Answer:

4.7\mu m

Explanation:

We are given that

Potential difference=V=154 V

Surface charge density=\sigma=29nC/m^2=29\times 10^{-5} C/m^2

Using 1 nC/cm^2=10^{-5} C/m^2

We know that

C=\frac{\epsilon_0A}{d}=\frac{Q}{V}=\frac{\sigma A}{V}

d=\frac{\epsilon_0V}{\sigma}

Where

\epsilon_0=8.85\times 10^{-12}C^2/Nm^2

Using the formula

d=\frac{8.85\times 10^{-12}\times 154}{29\times 10^{-5}}

d=4.7\times 10^{-6} m=4.7\mu m

Using 1\mu m=10^{-6} m

Hence, the spacing between the plates=4.7\mu m

What magnification would be obtained if an eyepiece with a focal length of 0.38 m was placed on telescope?
weqwewe [10]

Answer:

This question is incomplete

Explanation:

This question is incomplete because the telescope's focal length was not provided. The formula to be used here is

Magnification = telescope's focal length/eyepiece's focal length

The eyepiece's focal length was provided in the question as 0.38 m.

NOTE: Magnification can be described as the power of an instrument (in this case telescope) to enlarge an object. It has no unit and thus the two focal lengths mentioned in the formula above must be in the same unit (preferably meters since one of them is in meters already).

2 rocks of different masses roll down a hill at the same speed which rock has more kinetic energy small one or big one ???
Sophie [7]

Kinetic energy depends on the mass and the speed of a moving object.

If the speeds are equal, then the rick with more mass has more kinetic energy.
