The captain of a boat wants to travel directly across a river that flows due exst with a speed of 100 m/sHe starts from the sout

Salsk061 [2.6K]

Answer:

86.51° North of West or 273.49°

Explanation:

Let V' = velocity of boat relative to the earth, v = velocity of boat relative to water and V = velocity of water.

Now, by vector addition V' = V + v'.

Since v' = 6.10 m/s in the north direction, v' = (6.10 m/s)j and V = 100 m/s in the east direction, V = (100 m/s)i. So that

V' = V + v'

V' = (100 m/s)i + (6.10 m/s)j

So, we find the direction,Ф the boat must steer to from the components of V'.

So tanФ = 6.10 m/s ÷ 100 m/s

tanФ = 0.061

Ф = tan⁻¹(0.061) = 3.49°

So, the angle from the north is thus 90° - 3.49° = 86.51° North of West or 270° + 3.49° = 273.49°

I only need help on #15! Thanks!

Vanyuwa [196]

I would have to say that 'B' and 'D' are both correct.

Increasing the voltage that you're using to operate a circuit
causes the current in the circuit to increase. But current is
just the number of electrons that are flowing through it. So
right there, you have the increase in the number of charges.

Now, every electron that flows through the circuit gives up
some energy on the way. So if there are more electrons
making the trip, then more energy has been put into the circuit.

Jessica, I absolutely love your printing.
I wish I could print so clearly.

There is only one pressure this situation would be a "constant pressure" process. The work done by expanding gas is.

If the gas mileage of a Honda Civic car is 38 miles per gallon how many liters of gasoline would the car use to move from the Es

Troyanec [42]

Answer:

6.25

Explanation:

M = d/g........................ Equation 1

making g the subject of the equation,

g = d/M............................. Equation 2

Where M = mileage per gallon, d = distance move from Essex campus to Catonsville campus, g = amount of gasoline used

Given: M = 38 miles per gallon, d = 37.2 km

If 1 kilometer = 0.62 miles

Then, 37.2 km = 37.2×0.62 miles = 23.064 miles

Substituting these values into equation 2,

g = 38/23.064

g = 1.648 gallon

g ≈1.65 gallon

Thus,

If, 0.264 gallon = 1 liters.

Then, 1.65 gallon = 1.65×1/0.264 = 6.25 liters.

g = 6.25

Thus the car will use 6.25 liters of gasoline to move from the Essex campus to the Catonsville campus.
