Determine the mass of an object, if it requires a force of 6,000 kg: m/s2 to accelerate at the rate of 2 m/s^2
Answer:
The answer is 3000 kgStep-by-step explanation:
The mass of an object can be found by using the formula
[tex]m = \frac{f}{a} \\ [/tex]
f is the force
a is the acceleration
From the question we have
[tex]m = \frac{6000}{2} \\ [/tex]
We have the final answer as
3000 kgHope this helps you
[tex] \boxed{ \red{AnswEr:-}}[/tex]
Mass = 3000 kg★ GivEn :-
Force = 6000 kg • m/s^2Acceleration = 2 m/s^2★ To Find :-
The value of mass★ Solution :-
From Newton's 2nd law of motion we get the equation,
[tex]{ \boxed{ \red{ \sf{F =
m \times a}}}}[/tex]
where,
F = Force m = mass of the objecta = acceleration[tex] \implies \sf \: m = \dfrac{F}{a} [/tex]
Putting the values,
[tex] \implies \sf \: m = \dfrac{6000}{2} [/tex]
[tex] \implies \red{\sf \: m = 3000}[/tex]
Therefore, mass of the object = 3000 kg

Use the equation p= 8.31/v where p = pressure and V = volume.
What happens to the pressure as the volume approaches 0? Explain your reasoning.
Answer: pressure increases
Step-by-step explanation:
because Boyle's law states that pressure and volume have an inverse relationship, if we decrease volume the pressure will increase.
Another explanation: since volume approaches 0, we're dividing by a smaller number, and doing this gives us a larger value for pressure
Answer:
The pressure approaches infinity.
The function is undefined for V = 0.
There is an asymptote at V = 0.

Christo graphs AB with endpoints A( -3, -2 ) and B ( -1, -2 ) what are the endpoints of the image after a reflection of AB across the x axis?
1. (-3,2) and (-1,2)
2.(-3.-2) and (-1,-2)
3. (1,-2) and (3,-2)
4. (2,3) and (2,1)
5. none of the above
Answer:
1. (-3,2) and (-1,2)Step-by-step explanation:
Reflection over x-axis results in coordinate change as follows:
(x, y) → (x, -y), x-coordinate stays as is and y-coordinate changes its sign to oppositeGiven points:
A(-3, -2) and B(-1, -2)The image of AB will have coordinates:
A'(-3, 2) and B'(-1, 2)Correct choice is 1.
Answer:
(-3,2) and (-1,2)

Three cubic feet of seawater weigh 192 pounds.
What is the weight of the seawater in an aquarium that is 4.4 ft long, 2.5 ft wide, and 5.3 ft high?
Answer:
3731.2 pounds
Step-by-step explanation:
Aquarium will hold 4.4 * 2.5 * 5.3 = 58.3 cubic feet of sea water.
For 3 cubic feet of sea water, weight is 192 pounds
For 58.3 cubic feet of sea water,
( 192 * 58.3) / 3 = 11193.6 / 3 = 3731.2 pounds
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
Answer:
52 young calves
Step-by-step explanation:
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
The ration is given as:
adult milking cows to young calves
= 9 : 2
= 234 : x
= 9/2 = 234/x
x = Number of young calves
Cross Multiply
9 × x = 2 × 234
= x = 2 × 234/9
x = 468/9
x = 52
Hence, the number of young calves on the farm is 52.
