Answer:
Yes, when dealing with electricity as long as there is an input source there is always built up energy waiting to be used also known as kinetic energy. The fan is not spinning but if it were turned on it would spin instantaneously.
Answer:
-2200 N
Explanation:
Here we can use the impulse theorem, which states that the impulse exerted on Sarah (product of force and duration of collision) is equal to Sarah's change in momentum:
where
F is the average force
is the duration of the collision
m is the mass
is the change in velocity
In this problem:
m = 55 kg
Solving the formula, we find the force exerted by the seatbelt on Sarah:
And the negative sign means the direction is opposite to that of Sarah's initial motion.
The S strain Pneumococcus bacteria had a smooth surface because IT IS SURROUNDED BY A CARBOHYDRATE CAPSULE CALLED THE S STRAIN. The other form, the R strain has a rough surface and no capsule. It is only the S strain that exhibits virulence.
Answer:
In combination with hydrogen or with hydrogen and oxygen, they all form acids.
Explanation:
Non metal possesses
High ionization energies.
High electronegativities.
Poor thermal conductors.
Poor electrical conductors.
In combination with hydrogen or with hydrogen and oxygen, they all form acids. Example
H2o + Cl2 = Hcl + O2
