Answer:
east
Explanation:
15km east
_______________
X________
8km west
so you are where the xX is so you are still in the eastward direction
Answer:
6.36 105 J
Explanation:
In calorimetry all the energy given to a system is converted to heat and the equation for heat is
Q = m ΔT
The temperature can be in degrees Celsius or Kelvin since the interval between them is the same, substitute and calculate
Q = 1.9 4186 (373-293)
Q = 6.36 105 J
This heat equals the energy supplied
The force necessary to gain the velocity is 40 N.
The velocity gained by the object at the end of the second minute is 30 m/s.
<h3>Force of the object</h3>
F = mv/t
where;
- m is mass of the object = 200 kg
- v is velocity of the object = 60 m/s
- t is time of motion = 5 mins = 300 seconds
F = (200 x 60)/(300)
F = 40 N
<h3>Velocity of the object</h3>
F = mv/t
Ft = mv
v = Ft/m
where;
- m is mass = 600 kg
- F is force = 150 N
- t is time = 2 mins = 120 s
v = (150 x 120)/(600)
v = 30 m/s
Thus, the force necessary to gain the velocity is 40 N.
The velocity gained by the object at the end of the second minute is 30 m/s.

Pennsylvania or Texas are large producers of natural gas.
Answer:
All objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
Explanation:
Newton's Second Law, if I remember right.
