The angle of inclination is calculated using sin
function,
sin θ = 5 m / 20 m = 0.25
θ = 14.4775°
<span>The net force exerted is then calculated:
F net = m g sin θ = 20 * 9.8 * 0.25 </span>
F net = 49N
<span>Work is product of net force and distance:
W = F net * d = 49 * 20 </span>
<span>Work = 980 J </span>
In an extremely simplified explanation,
What happens is that the steam (heat) that is generated by the burning of coal is used to rotate the motor of the steam engine.
The momentum of the rolling ball will have less momentum than before the collision and the stationary ball will have more momentum after the collusion.
The amount of blood that flows through the venae cavea of the adult is 3750 ml more than that of the child.
<h3>What is flow rate?:</h3>
This is the volume of fluid flowing in a vessel per unit time.
First, we need to get the volume of blood flowing through the venae cavae of the adult and the child in 1 hour, then subtract the volume of blood for the child from that of the adult.
Using,
- V = F'm................ Equation 1
Where:
- V = Volume of the blood
- F' = Flow rate
- m = mass of blood.
For the Adult,
Given:
Substitute these values into equation 1
For the child,
Given:
Substitute these values into equation 1 also
The amount of blood that flows more through the adult than the child is
- A = 5250-1500
- A = 3750 ml.
Hence, the amount of blood that flows through the venae cavea of the adult is 3750 ml more than that of the child.

Answer:
783 grams
Explanation:
Here mass is given in kg
Some of the prefixes of the SI units are
1 gram = 10⁻³ kilogram
1 milligram = 10⁻⁶ kilogram
1 microgram = 10⁻⁹ kilogram
1 nanogram = 10⁻¹² kilogram
The number is 0.783
Here, the only solution where the number of significant figures is three is gram. If any other prefix is chosen then the significant figures will increase
So, 0.783 kg = 783 grams
