Answer:
13800 N
Explanation:
Impulse is the product of average force and time expressed as I=Ft where I is the impulse which results into change in momentum, F is the average force and t is the time of impact. Making F the subject of formula then

Substituting I with 13.8 N.s and time, t witg 0.001 s then the average force is calculated as

Therefore, the average force is equivalent to 13800 N
Answer:
C: Valence electrons are transferred from a metal to a nonmetal
Explanation:
In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Answer: lambda
, nu
, and 100E
Explanation:
The energy
of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency
On the other hand, we have an expression that relates the frequency of the photn with its wavelength
:
(2) where
is the speed of light
Substituting (2) in (1):
(3) This is the energy for a single photon
For 100 photons, the energy is:
(3)
Where the wavelength and the frequency of the light remains constant.
Therefore, the answer is:
,
, and 100E
Answer:
W = 0.678 rad/s
Explanation:
Using the conservation of energy:

Roll up and hill without slipping is the sumatory of two energys, rotational and translational, so:

where I is the moment of inertia, W the angular velocity at the base of the hill, m the mass of the ball, V the velocity at the base of the hill, g the gravity and h the altitude.
First, we will find the moment of inertia as:
I =
where m is the mass and R the radius, so:
I =
I = 36.26 Kg*m^2
Then, replacing values on the initial equation, we get:

also we know that:
V =WR
so:

Finally, solving for W, we get:

W = 0.678 rad/s
