Why is the answer C?

4vir4ik [10]

Explanation:

We want to find the statement that is proven by the fact that the balls reach the same height.

A isn't supported by the evidence. Balls can reach the same height without having the same initial speed.

B isn't supported by the evidence. Balls can reach the same height without having the same launch angle.

C is supported. Projectiles spend the same amount of time going up as they do coming down, so if two projectiles reach the same height, then they must spend the same amount of time in the air.

D isn't supported by the evidence. Balls thrown at the same speed and complementary angles have the same range but different heights.

E isn't supported by the evidence. The mass of the ball doesn't affect the height.

Based on the replacement reaction, what would the products of the reaction be?

fredd [130]

Answer:

Explanation:

BeSO₄ + 2NH₄OH → Be(OH)₂ + (NH₄)₂SO₄

In a replacement reaction, an atom or ion substitutes or replaces another in a reaction. We can have single replacement or double replacement reaction.

The above is a double replacement reaction. In this type of reaction, partners are exchanged to form compounds. In a single replacement, one substance is replacing another.

If the density of the fuel is 0.821 g/ml, what mass of fuel has the airplane taken on?

bija089 [108]

<em>Mass of fuel has the airplane took on = 167.89 kg</em>

$\boxed{\boxed{\bold{Further~explanation}}}$

Density is a quantity derived from the mass and volume

density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass

The unit of density can be expressed in g / cm3 or kg / m3

Density formula:

$\large{\boxed{\bold{\rho~=~\frac{m}{V} }}}$

ρ = density

m = mass

v = volume

A common example is the water density of 1 gr / cm3

If we look at fuel capacity data such as Airbus which has a maximum capacity of 204, 5 liters then the mass of fuel it carries is

ρ = 0.821 gr / ml = 0.821 kg / l

mass = ρ . V

mass = 0.821 kg / l . 204.5 liters

mass = 167.89 kg

So the mass of fuel carried by aircraft is 167.89 kg

1. how are weather data used to make forecasts?

andreev551 [17]

1. Weather data is used to make forecasts first by analyzing a weather report to discover it's parts, the purpose of it is to include a variety of weather map symbols, predict weather events and produce mock forecasts which the intent shows how data is collected and analyzed. The same techniques are used to analyze weather data. By creating a web from the start, they'll be able to complete an assessment where they'd be creating another web which outlines the steps a forecaster takes to produce a forecast.
2. Temperature is the measurement of the amount of energy in an object or area, dew point is the temperature that the air must be cooled without adding or eliminating water vapour in order to reach saturation. Air pressure is what is controlled by the air pressure regulator in whatever the air is flowing through.
