Answer:
250
Explanation:
impulse calculator internet
The electric field intensity generated by a single point charge is given by
where
k is the Coulomb's constant
q is the charge
r is the distance from the charge
In this problem, the charge is 
and we are asked to calculate the field at distance 
, so the electric field is
Answer:
B.the same as Lily's.
Explanation:
When a disc is rotating on its axis uniformly with some angular velocity , every particle on it rotates with the same angular velocity , because every particle on it completes a rotation simultaneously . So in one rotation they take same time . Hence particles whether on the outer edge or near the axis , all have same angular velocity .
They but differ due to their different linear velocity . Linear velocity of particle near outer edge have greater magnitude. .
In a cold pack, an endothermic reaction draws heat from the surroundings, although there are several different types of cold packs, some with different reactions.
centimeter or millimeter.
Explanation:
The unit of length most suitable for measuring the thickness of a cell phone is centimeter or millimeter.
Length refers to how long a material is.
- There are different units of length.
- Smaller units that are microscopic are used to measure length dimensions that are very small
- For example, nanometre is used to express microscopic length values.
- Centimeters and millimeters are used for small dimensions that we can easily see.
- Longer lengths can take the order of a yard, kilometer, miles e.t.c
