A block of aluminum has a volume of 15.0 ml and a mass of 50.5 g. the density is: 3.36 g/ml
To solve this problem the density formula and the procedure that we have to use is:
d = m/v
Where:
- v= volume
- d= density
- m= mass
Information about the problem:
Applying the density formula we get:
d = m/v
d = 50.5 g/15.0 ml
d= 3.36 g/ml
<h3>What is density?</h3>
It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.
What is volume?
It is the space occupied by a body, it is calculated by multiplying its dimensions, for example: length, height and width.

Answer:
14 m/s
18 m/s
22 m/s
Explanation:
The car is moving at constant acceleration, so we can find its velocity at time t using the equation:
where
u = 10 m/s is the initial velocity
is the acceleration
t is the time
Substituting the different times, we find:
At t = 2 s:
At t = 4 s:
At t = 6 s:
Answer:
The charge flos through the coil is 0.023C
Explanation:
To solve this problem, it is necessary to apply the concepts related to Faraday's Law in which it is possible to calculate the emf Voltage induced due to a charge in a magnetic field
and Ohm's Law for the calculation of the current based on a given load over time.
Our data are given by:
Where
N is the number of loops, A the area and R the Resistance.
The change in magnetic field can be calculated as,
The Faraday's law of electromagnetic induction is given by definition as,
In the other hand Ohm's law says:
Equating both equations we have
We can re-arrange the equations to solve q, then
Therefore the charge flos through the coil is 0.023C
Explanation:
because it doesn't depend upon other unit like kg meter and second
It is the the ecrins of light
