Answer:
d = 39.7 km
Explanation:
initial position of the boat is 45 km away at an angle of 15 degree East of North
so we will have
after some time the final position of the boat is found at 30 km at 15 Degree North of East
so we have
now the displacement of the boat is given as
so the magnitude is given as
ENGLISH:
It distinguishes between the fermions, which are particles of matter, and the bosons, which carry forces. The matter particles include six quarks and six leptons. The six quarks are called the up, down, charm, strange, top and bottom quark. ... All of these matter particles fall into three “generations.”

Los seis quarks se denominan quark arriba, abajo, encanto, extraño, superior e inferior. ... Todas estas partículas de materia se dividen en tres "generaciones".
The increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
5000 = 225 × 0.385 × ∆T
5000 = 86.63∆T
∆T = 5000/86.63
∆T = 57.72°C
Therefore, the increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.

Answer:
Explanation:
ratio of the forces is equal to the ratio of the surface areas
which is another way of saying the pressure is constant in the system
2000(9.8) / 500 = A / 10
A = 2000(9.8)(10) / 500 = 392 cm²
Answer:
The field losses a total of 55.814 litres of water in an hour.
Explanation:
As the complete question is not given here, the average rate of water loss is not given here which is found in normal conditions as 1.67 mL/m2.
Now the average rate of water loss per minute is 1.67 mL/m2
So the average rate of water loss per minute for 557 m2 is 1.67*557=930.19 mL
So 930.19 mL of water is lost from the field in 1 minute, for the calculation of water lost in an hour, the value is given as 60*930.19 =55811.4 mL or 55.814 litres.
