A tsunami wave is different than a normal wave because it is caused by an sudden displacement in the ocean. a earth quake below the ocean floor, a landslide, or a meteorite impact. normal waves are caused by the wind, weather and tides, unlike tsunamis. the long wavelengths from the impact from a earthquake can make the wave slow down and increase the amount of water + height for the wave, making a larger impact wave, a tsunami

The total charge a battery can supply is rated in mA⋅hmA⋅h, the product of the current (in mA) and the time (in h) that the batt

Nat2105 [25]

Answer:

118800 seconds

Explanation:

Given :

Voltage, V = 1.2 V

Resistance, R = 22 Ω

Applying Ohm's law, we get

Voltage, V = IR

Current $I=\frac{V}{R}$

$I=\frac{1.2}{22}$

I = 0.0545 A

Rate = 1800 mAh

Time taken, $t=\frac{1800 \times 10^{-3}}{0.0545}$

= 33 hr

= 118800 s

A car travels 90 meters north in 15 seconds. Then turns around and travels at 40 meters south in 5.0 seconds. what is the averag

Viefleur [7K]

Average velocity = (displacement) / (total time)

Displacement = distance and direction between
the starting point and the end point

The car travels 90 meters north, then 40 meters south.
So it ends up 50 meters north of where it began.

Displacement = 50 meters north
Total time = (15 + 5) = 20 seconds

Average velocity = (50 meters north) / (20 seconds)

= 2.5 m/s north

Why does a child in a wagon seem to fall backward when you give the wagon a sharp pull forward? 15. What force is needed to acc

slavikrds [6]

Answer:

Force, F = 77 N

Explanation:

A child in a wagon seem to fall backward when you give the wagon a sharp pull forward. It is due to Newton's third law of motion. The forward pull on wagon is called action force and the backward force is called reaction force. These two forces are equal in magnitude but they acts in opposite direction.

We need to calculate the force is needed to accelerate a sled. It can be calculated using the formula as :

F = m × a

Where

m = mass = 55 kg

a = acceleration = 1.4 m/s²

$F=55\ kg\times 1.4\ m/s^2$

F = 77 N

So, the force needed to accelerate a sled is 77 N. Hence, this is the required solution.
