Answer:
FLASH FLOODS CAN CAUSE VEHICLES TO FLOAT AND FILL WITH WATER, TRAPPING AND DROWNING PEOPLE. WHILE ESPECIALLY DANGEROUS AT NIGHT AND IN DEEP WATER, EVEN ____ INCHES OF WATER CAN FLOAT SOME SMALL CARS.
The Answer is SIX Inches.
Explanation:
Flash floods: are short-term events and are associated with short, high-intensity rainfall which occur when creeks that are normally dry fill up and other creeks overflow. Densely populated areas have a high risk of flash floods. Water levels in flash floods can rise one foot in five minutes making Six inches of water able to reach the bottom of most passenger cars. Moving water will exert pressure on a car. The car floats downstream when stream force exceeds the friction force, the car will be carried when bouyancy force (which is the upward force exerted by any fluid upon a body placed in it) is greater than vehicle weight.
Answer:
Explanation:
change in flux = no of turns x area of coil x change in magnetic field
= 163 x π 2.65² x 10⁻⁴ x ( .481 - 0 )
= 1728.84 x10⁻⁴ weber
rate of change of flux = change in flux / time
= 1728.84 x10⁻⁴ / .149
= 11603 x10⁻⁴ V .
volt induced = 1.16 V
current in the circuit
= volt induced / resistance
1.16 / 10.7 = .1084 A
energy dissipated = i²Rt where i is current , R is resistance and t is time.
= .1084² x 10.7 x .149
= .018734 J
= 18.73 mJ .
The magnitude of the average force exerted on the ball by the wall is calculated below.
The average force exerted by the ball on the wall is 3 N
Explanation:
Given:
mass of the ball (m)=0.10 kg
speed (v) =3.0 m/s
time taken(t) =0.01 seconds
To calculate:
Average force(F) exerted by ball on the wall
We know;
F=(m×v)÷t
F=(0.10×3.0)÷0.01
<u><em>F=3 N</em></u>
Therefore the average force exerted by the ball on the wall is 3 N

Explanation:
As Merrill watches his finger with both eyes open as he brings his finger closer to his nose, he feels his eye muscles working. This shows that her eyes Muscles have both accommodation and convergence.
Accommodation and convergence allows us to view objects both near and at far without double vision.
