Answer:
At 37 degrees celsius, atoms of a He (g) sample would have the greatest average Kinetic energy.
Explanation:
Answer:
b
Explanation:
This solution assumes that there are no air resistance and no wind and thus no drag to the object itself
Based on the information given:
With that information at hand, we use the physics equation:
Now let's plug in all the known variables and solve.
.
Thus it takes the food packet approximately 6.389 seconds to hit the ground.
Hope that helps!
B. hills
C. using the heater
Answer: refueling too often
Explanation:
the answer for this problem is A
tank at a constant rate. After the hose was on for
5 minutes, the tank was exactly half full. After
the hose was on for 30 minutes, the tank was
three-quarters full. How many minutes did it take
after the hose was turned on for the tank to be
completely filled with water?
Considering the definition and sum of complex numbers, the sum (9 + 4i) + (–1 - 7i) gives as a result 8 -3i.
Complex numbers are combinations of real numbers and imaginary numbers.
In other words, complex numbers are numbers that have a real part and an imaginary part.
The most common representation of a complex number is the sum of a real part and an imaginary part. At the same time, the imaginary part is divided between the imaginary part and the imaginary unit:
z = a + bi
where
This expression is called the binomial form of the complex number z.
To add two or more complex numbers, you simply have to add the real and imaginary parts separately. That is, being z1 = a + bi and z2 = c + di, the sum of both complex numbers is calculated as:
z1 + z2 = (a + c) + (b + d) i
In this case, to obtain 8 -3i you have to sum:
(9 + 4i) + (–1 – 7i)= (9-1) + (4-7)i= 8 - 3i
So, the sum (9 + 4i) + (–1 - 7i) gives as a result 8 -3i.
