Answer:
The electric charge, q (in coulomb units) = 5004 C
Given:
The charge stored as printed on NiMH battery, q = 1390 mAh
Solution:
To express the amount of electric charge printed on the battery in milli-ampere-hour (mAh) in coulomb, we will do simple conversion of milli amperes in ampere and hours in seconds:
1 mA = 
1 hour = 
Also, we know that the rate of flow of charge is electric current, I:
I = 
⇒ q = [tex]I\times t[tex] (1)
where
q = electric charge
I = current
t = time taken for flow of current
Using eqn(1), we get:
q = [tex]1390\times 10^{-3}\times 60\times 60[tex]
q = 5004 A-s = 5004 C
B) low energy, because red is on the far left of the electromagnetic spectrum.
Hey JayDilla, I get 1/3. Here's how:
Kinetic energy due to linear motion is:
where
giving
The rotational part requires the moment of inertia of a solid cylinder
Then the rotational kinetic energy is
Adding the two types of energy and factoring out common terms gives
Here the "1" in the parenthesis is due to linear motion and the "1/2" is due to the rotational part. Since this gives a total of 3/2 altogether, and the rotational part is due to a third of this (1/2), I say it's 1/3.
Answer:
45 W
Explanation:
First of all, we need to find the work done by the person to lift the bag. The work done is given by
where
F = 75.0 N is the force applied
d = 1.50 m is the displacement of the bag
Substituting numbers into the formula,
Now we can find the power used, which is given by
where
t = 2.50 s is the time taken
Again, using W=112.5 J, we find
According to the chart concluded by Charity's observation, her rabbit prefers lettuce over celery and carrots and majority of rabbit species follows the same.
Answer: Statement A
<u>Explanation:</u>
As per the biological observations, it's is proven that leafy vegetables such as lettuce is worth for rabbits health as compared to carrots being involved in their daily diets as it contains sugar. According to the observations that Charity has gone through a month for her pet rabbit, it seems that her rabbit is most likely preferring lettuce over carrots and celery.
Talking about celery, it's not among the leafy kinds of rabbit's diet and should only worth of only 15% of space in daily diet. Although rabbits often eat celery, but most of the species primarily rely on lettuce and parsley which seems the case with Charity's pet. Hence, the statement A is likely to be the best answer according to the observations that the rabbit prefers lettuce over carrot and celery.
