Answer: Tornado

Explanation:

A tornado is a type of wind storm which exhibit a tall funnel shaped column of air. The air spins round very fast in tornado and causes a lot of damage. The powerful wind column makes a wind spiral possibly around a center exhibiting a low atmospheric pressure. These storms are also called as twisters. The objects, trees, buildings and human beings which come in contact with the tornado get affected and destroyed.

You're talking about a <em>tornado</em>.

It's not so much the low pressure that's so dangerous in the center of a tornado. It's more a matter of the high winds that are <em>caused </em>by the low pressure.

Answer:

Explanation:

Remark

If, when it reaches its maximum height where the PE is the greatest, that the maximum energy is when the ball is first kicked. That would mean its starting energy is 10 Joules.

Formula

KE = 1/2 m v^2

Givens

KE = 10 J

m = 0.2 kg

v = ?

Solution

10 = 1/2 * 0.2 * v^2

10 * 2 = 0.2 * v^2

20 = 0.2 * v^2

20/0.2 = v^2

100 = v^2

v = 10 m/s

What is the upward force that balances the weight of an object on a surface

Alina [70]

Answer:

The support force/ Normal reaction force

Explanation:

Refer to Newtons third law.

"The third law states that when a force acts on a body due to another body, then an equal and opposite force acts simultaneously on that body"

Since we have a downward force acting on your object, in this case gravity/weight, there is an equal and opposite force given off by the surface the object is on. This is called the support force or the normal reaction force

The Goodyear blimp Spirit of Akron is 62.6m long and contains 7023m^3 of helium. When the temperature of the helium is 285 K, it

andre [41]

Answer:

1328.7032 kg

Explanation:

P = Pressure = 112 kPa

T = Temperature = 285 K

V = Volume = 7023 m³

R = Gas constant = 8.314 J/mol K

From the ideal gas law we have

$PV=nRT\\\Rightarrow n=\dfrac{PV}{RT}\\\Rightarrow n=\dfrac{112000\times 7023}{8.314\times 285}\\\Rightarrow n=331960.04203\ moles$

The mass of gas is given by

$m=n\times MW_{He}\\\Rightarrow m=331960.04203\times 4.0026\times 10^{-3}\\\Rightarrow m=1328.70326\ kg$

The mass of helium in the blimp is 1328.7032 kg

To find the acceleration of a glider moving down a sloping air track, you measure its velocities (V1 and V2) at two points and t

jeka94

Answer:

(a). The average acceleration is 0.08 m/s².

(b). The uncertainty in the acceleration is ±0.0135 m/s².

Explanation:

Given that,

Initial velocity $v_{1}=0.21\pm 0.05\ m/s$

Final velocity $v_{2}=0.85\pm 0.05\ m/s$

Time $t = 8.0\pm 0.1\ sec$

(a). We need to calculate the average acceleration

Using formula of acceleration

$a=\dfrac{v_{2}-v_{1}}{t}$

Put the value into the formula

$a=\dfrac{0.85-0.21}{8.0}$

$a=0.08\ m/s^2$

(b). We need to calculate the uncertainty in the velocity

Using formula of the uncertainty

$\dfrac{\Delta v}{v}=\dfrac{\Delta v}{v_{2}-v_{1}}$

Put the value into formula

$\dfrac{\Delta v}{v}=\dfrac{0.05+0.05}{0.85-0.21}$

$\dfrac{\Delta v}{v}=0.15625$

We need to calculate the uncertainty in the time

Using formula for time

$\dfrac{\Delta t}{t}=\dfrac{0.1}{8.0}$

$\dfrac{\Delta t}{t}=0.0125$

We need to calculate the uncertainty in the acceleration

Using formula for acceleration

$\dfrac{\Delta a}{a}=\dfrac{\Delta v}{v}+]\dfrac{\Delta t}{t}$

Put the value into the formula

$\dfrac{\Delta a}{a}=0.15625+0.0125$

$\dfrac{\Delta a}{a}=0.16875$

$\Delta a=0.16875\times0.08$

$\Delta a=\pm0.0135$

Hence, (a). The average acceleration is 0.08 m/s².

(b). The uncertainty in the acceleration is ±0.0135 m/s².
