Answer: A. Reacts with certain metals.

D. Reacts with baking soda to produce carbon dioxide.

Explanation:

The bases are the substances that are in the form of aqueous solution. These solutions liberates the hydroxide ions in water. They are slippery in touch, they are bitter in taste, they change color in the presence of indicators and react with acids so as to neutralize it.

The bases do not react with metals like acids do. The baking soda is a base which reacts with the acid to form carbon dioxide, salt and water. The base does not react with baking soda to form carbon dioxide.

A diver shines a flashlight upward from beneath the water (n = 1.33) at a 32.7° angle to the vertical. At what angle does the li

suter [353]

Answer:

45.93°

Explanation:

The angle of incidence is given as 32.7°

The refractive index of the water that is $n_1=1.33$

Refractive index of the air that is $n_2=1$ (because the refractive index of air is 1 )

We have to find the angle at which the light leave the water means angle of refraction

So according to snell's law $n_1sini=n_2sinr$

$1.33sin32.7=1\times sinr$

$sinr=0.7185$

r =45.93°

So the light leave the water at an angle of 45.93°

Answer:

Speed at the bottom of the roller coaster = 49.79 m/s

Explanation:

A new ride being built at an amusement park includes a vertical drop of 126.5 meters. Starting from rest, the ride vertically drops that distance before the track curves forward.

We have to find the speed at the bottom.

Here the gravitational energy fully converts to kinetic energy, so we equate it.

Gravitational energy = $m\times g\times h$

Kinetic energy = $0.5 \times m\times v^{2}$

$m\times g\times h$ = $0.5 \times m\times v^{2}$

$9.8\times 126.5 = 0.5\times v^{2}$

$v^{2}$ = 2479.4

Velocity, v = 49.79 m/s

You used a telescope and other mathematics to discover that Jupiter is 5.20 au from the sun. Use the equation to find its orbita

meriva

Answer:

11.9 years

Explanation:

We can find the orbital period by using Kepler's third law, which states that the ratio between the square of the orbital period and the cube of the average distance of a planet from the Sun is constant for every planet orbiting aroudn the Sun:

$\frac{T^2}{r^3}=const.$
