Answer: Convection is the transfer of heat in fluids such as liquids and gases.
Explanation: Any difference in their temperature will cause a transfer of heat. For convection warm fluids rises since it becomes less dense and cooler fluids sinks.
Answer:
(a) 1294.66 m
(b) 88.44°
Explanation:
d1 = 580 m North
d2 = 530 m North east
d3 = 480 m North west
(a) Write the displacements in vector forms
The resultant displacement is given by
magnitude of the displacement
d = 1294.66 m
(b) Let θ be the angle from + X axis direction in counter clockwise
θ = 88.44°
Answer:
x = 16 [m]
Explanation:
This problem can be solved using the following equation of kinematics.
where:
Vf = final velocity [m/s]
Vo = initial velocity = 5 [m/s]
a = acceleration = 3 [m/s²]
t = time = 2 [s]
Now we can find the displacement using the following equation of kinematics.
The total kinetic energy of the system after collision is 223.5J
In elastic collision kinetic energy and momentum are conserved.
According to the question
mass of object a = 25kg
mass of object b = 25 kg
initial velocity of a u1 = 5.98 m/s
initial velocity of b u2 = 0
so from momentum conservation-
mau1 + mbu2 = (m1+m2)v
25kg × 5.98m/s + 25×0 = (25+25)v
v = 2.99 m/s
Now the total kinetic energy after the collision will be:
final kinetic energy = 1/2 (m1+m2) v²
= 1/2 (25+25)× (2.99)²
= 223.5 J
Thus, total kinetic energy of the system after collision is 223.5J

Answer:
Northeast
Explanation:
I'm not sure if there's some fancy thing you have to do, but if there's no cardinal compass given, I think it's safe to assume that the answer is based off of one. Therefore, up is north, right is east, so Maple Creek flows to the northeast.
However, if they do give you one where, say, north points downwards, the creek would flow to the southwest. But again, from what is shown, there's no compass, so NE is your best guess here.
