HELP. what is the speed of a boat in miles per hour that travels 20 miles in 45 minutes?
Minchanka [31]

Average speed  =  (distance covered)  /  (time to cover the distance)

                          =          (20 miles)   /   (45 minutes)

Multiply that fraction by  (60 minutes / 1 hour) .
This is equal to ' 1 ', so you won't change anything except the units.

                         =          (20 miles / 45 minutes) times (60 minutes / 1 hour)

Multiply the fractions, then cancel 'minutes' out of
the numerator and denominator.

     =  (20 miles  x  60) / (45  x  1 hour)

     =     (20 x 60 / 45)  miles/hour

     =        26-2/3 miles/hour .

If we double the resistance in a circuit but keep the current in it constant, the power dissipated by that circuit will
7nadin3 [17]
By definition, the power is equal to the product of the current high squared by the value of the resistance.
 In other words:
 P = I ^ 2 * R
 where,
 I: Current
 R: resistance
 If we double the resistance in a circuit but keep the current in it constant, then:
 P = (I ^ 2) * (2 * R)
 P = 2 * (I ^ 2 * R)
 The power increases twice.
 answer:
 The power dissipated by that circuit will increase twice

If an aircraft slows down from 160 km/h to 10 km/h with a uniform of 5 m/s2
marusya05 [52]

Explanation:

10km/h = 10×10/36=25/9m/sec

160km/h= 160×10/36=400/9

v=a×t

t=v/a

t=(400/9-25/9)/5

t=(125/3)/5=25/3=

An elephant of mass 2800kg has feet of average area of 200 cm2. A vulture of mass 12 kg walks beside the elephant on a muddy are
hoa [83]

Explanation:

The formula we are going to use is

Pressure = F/A

Elephant:

First, we need to convert weight into newtons.

1kg=9.8 newtons, so 2800kg × newtons = 27440newtons

For 4 feet= 200×4= 800cm^2

Convert the area to meter squared using the following:

1 centimeter squared = 0.0001 meters squared

800cm^2×0.0001= 0.08m^2

Pressure=F/A

Pressure= 27440/0.08

The pressure exerted on the ground by the elephant is 343000 Pascals.

Vulture:

12kg×9.8=117.6newtons

for 2 feet= 2.0×2=4cm^2

4×0.0001=0.0004m^2

117.6/0.0004= 294000 Pascals

To compare the pressure, just do a ratio of the elephant's pressure to vulture's pressure.

343000/294000≈ 1.17

So the pressure is about 1 times bigger.

Keep in mind that the elephant has 4 feet, which help to increase the area which in turn decrease the pressure.
