When the leveling bulb is higher than the water level, the pressure in the system is greater than atmospheric pressure.

1 answer:

4 0

When the leveling bulb is higher than the water level, the pressure in the system is greater than atmospheric pressure. This statement is true.

In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area. A 42-pound box with a bottom area of 84 square inches will impose pressure on a surface equal to the force divided by the area it is applied to, or half a pound per square inch.

Atmospheric pressure, which is roughly 15 pounds per square inch at sea level, is the weight of the atmosphere pressing down on each unit area of the Earth's surface. Pascals are used to express pressure in SI units; one pascal is equivalent to one newton per square meter. Almost 100,000 pascals of atmospheric pressure are present.

The color of light emitted by a hot, solid object depends on ______.

nadya68 [22]

Answer:

The correct option is (A).

Explanation:

When the temperature of the hot solid object increases then the radiation which emits from it gets shifted to smaller wavelength or higher frequencies. The hot appears red color.

The total energy emitted of a hot solid object is directly proportional to the fourth power of the temperature of the black body.

For example, when we switch on the light bulb, initially the radiation of the bulb appears dimmer. Then, it will become brighter. Then, it will turn yellow and then it becomes even white.

The color of the light emitted by a hot solid object depends on the temperature of the object.

Therefore, the correct option is (A).

Complete Question

Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?

Answer:

The time it would take at the given speed is $x = 43.00 \ minutes$

Explanation:

From the question we are told that

The time taken to exist the highway is $t = 55 min$

The distance to the exist is $d = 43\ mi$

Alberta speed is $v = 60 mph$

The time it would take travelling at the given speed is mathematically represented as

$t_z = \frac{d}{v}$

substituting values

$t_z = \frac{43}{60}$

$t_z = 0.71667\ hrs$

Converting to minutes

1 hour = 60 minutes

So 0.71667 hours = x minutes

Therefore

$x = 0.71667 * 60$

$x = 43.00 \ minutes$

Hydrogen/hydronium ion concentration

Valentin [98]

Answer:

Pure water is considered to neutral and the hydronium ion concentration is 1.0 x 10-7 mol/L which is equal to the hydroxide ion concentration. So the pH is the -log of the [hydronium ion].

30 points answer ASAP please

djverab [1.8K]

Explanation:

Momentum of the system is a constant when there aren't external forces..

So,When first Balls velocity is went down to zero... its momentum is also zero and beacause momentum should be a constant...now second ball must have a momentum of 20 kg * m/s

Select the correct answer. A ball is thrown straight down from the top of a building at a velocity of 16 ft/s. The building is 4

BartSMP [9]

Answer:

The ball takes 5s to reach the ground

Explanation:

in order to solve this problem we use the kinematics equation with gravity as acceleration:

$h=v_0t+1/2*gt^2$

we replace the values

$0=1/2*32t^2+16t-480$

We solve this quadratic equation:

t=5s

t=-6s (this solution has not physical sense)
