Answer:
E = 18750 J
Step-by-step explanation:
The question is "If a car has a mass of 1,500 kg and a speed of 5 m / s, what is the kinetic energy of a car?"
Mass, m = 1500 kg
Speed, v = 5 m/s
We need to find the kinetic energy of the car. The formula for kinetic energy is given by :

So, 18750 J is the kinetic energy of the car.
Answer:
Ok first of all you start out splitting the shape into seperate rectangles, in this case 2. take those 2 rectangles and find the area of them. Say we start from the smaller rectangle. 2 x 4 = 8 so the area of the smaller rectangle is 8. Keep that in mind. Next we have to multiply 10 x 5 because that is the labeled number of meters and that equals 50. So add 50 + 8 = 58
Step-by-step explanation:
Your answer is 58 meters
Really hope i helped and have a wonderful day! :)
For numbers 710-720 there are 4 integers (712,714,716 and 718)
numbers 720-730 there are 3 (724,726,728)
for 730-740 , 750-760, there are 4 in each case.
740-750 , 760-770, 780-790 there are 3 in each case
and for 790-800 there are 4. None for 770-780.
so for numbers 700 - 800 we have a total of 28 integers which fit the requirements.
The number for integers 800 to 900 and 900 to 999 will also be 28 in each case.
Answer is 3*28 = 84 answer.
Answer:
140.32mL per hour
Step-by-step explanation:
Rate of leakage of nitrogen ballon = 75 mL/h
Rate of leakage of helium ballon = x
Molar mass of nitrogen= Mn = 14
Molar mass of helium = Mh = 4
Effusion formula
Rate of effusion of helium/ Rate of effusion of nitrogen= √(Molar mass of nitrogen/Molar mass of helium)
Rate of effusion of helium = 75mL/h * √(14/4)
= 140.32mL/h
