definition of force

Explanation:

It states that "the rate of change in momentum is proprtional to the force applied"

[tex]{ \rm{momentum = mass \times velocity}} \\ [/tex]

• from the law stated:

[tex]{ \rm{ \frac{ \delta momentum}{time} = force}} \\ \\ { \rm{ \frac{mv - mu}{time} = force}} \\ \\ { \rm{ \frac{mass(v - u)}{time} = force}} \\ \\ { \rm{mass \times \frac{(v - u)}{time} = force }}[/tex]

• from first newton equation:

[tex]{ \boxed{ \tt{ \frac{v - u}{t} = acceleration}}} \\ [/tex]

• therefore

[tex]{ \rm{mass \times acceleration = force}} \\ \\ { \boxed{ \rm{force = mass \times acceleration}}}[/tex]

what is asked give brief explanation about question

The horizontal distance that the cannonball will travel is 383.33m

In order to find the horizontal distance, we will use the formula for calculating the range expressed as:

[tex]R = u\sqrt{\frac{2H}{g} }[/tex] where:

u is the velocity

H is the height

g is the acceleration due to gravity

[tex]R = 120\sqrt{\frac{2(50)}{9.8} }\\R = 120\sqrt{\frac{100}{9.8} } \\R=120\times 3.1943\\R=383.33m[/tex]

Hence the horizontal distance that the cannonball will travel is 383.33m

Answer:

2m/s^2

Explanation:

A=(u-v)/t

where u=final velocity and v=initial velocity and t=time

therefore u =70 and v=0 because the question said velocity of rest and finally t=35

so, (70-0)/35= 70/35=2

The characteristics of the ionic bonds allows to find the results for the question about which compound are ionic is:

    d) Compounds D and A.

Chemical compounds are formed by atoms linked by electrostatic forces, where one of the elements gave up some electrons and the other element acquired these electrons, the two atoms being in an ionic state, consequently the bond is strong and has several characteristics:

In these characteristics, let's analyze the compounds in the table.

Let's review the different alternatives:

a) False. Compound A and B has a low melting point.

b) False. The B and C compounds have low melting points.

c) False. Compound C has a low melting point.

d) True. The two compounds meet all the characteristics of ionic compounds.

In conclusion with the characteristics of the ionic bonds we can find the results for the question about which compound are ionic is:

Explanation:

A ball rolls horizontally off the cliff at a speed of 30 m/s. It takes 7 seconds for the ball to hit the ground. What is the height of the cliff and the horizontal distance traveled by the ball?

S = (1/2)*9.8 m/s^2 * 7^2 = 240.1 m if the ball is very dense so air resistance, and therefore terminal velocity, can be ignored.

S = v * t = 30 m/s * 7 s = 210 m for the horizontal distance, again assuming negligible air resistance.

Height above the ground is the ball after the ball has fallen for 1 second is 210 m.

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

A ball rolls horizontally off the cliff at a speed of 30 m/s. It takes 7 seconds for the ball to hit the ground.

S = (1/2)*9.8 m/s² * 7² = 240.1 m if the ball is very dense so air resistance, and therefore terminal velocity, can be ignored.

S = v * t = 30 m/s * 7 s = 210 m for the horizontal distance, again assuming negligible air resistance.

Height above the ground is the ball after the ball has fallen for 1 second is 210 m.

Explanation:

The average velocity of the car traveling south and later returned to the starting point is 0.

Average velocity is defined as the change in displacement per change in the time of motion.

Average velocity is calculated as follows;

[tex]v = \frac{\Delta x}{\Delta t} = \frac{x_2 - x_1}{t}[/tex]

Let the initial displacement of the car, x₁ = 20 m

Let the final displacement of the car, x₂ = 20 m (since the car returned to the starting point).

The average velocity is calculated as;

[tex]v = \frac{x_2 - x_1}{t} = \frac{20 - 20}{5} = 0[/tex]

Thus, the average velocity of the car traveling south and later returned to the starting point is 0.

Answer:

In most plants, the leaves are the main food factories. They capture the sun's energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.

Answer:

6.86g/mL

Explanation:

The density of the metal would be approximately 6.859 grams per milliliter (g/mL).

Given that the mass (m) is 78.2 g and the volume (V) is 11.4 mL, we can plug these values into the formula:

Density is a physical property that quantitatively expresses how much mass is contained within a given volume of a substance. In other words, it is a measure of how tightly packed the particles or molecules of a material are. Mathematically, density is defined as the mass of an object (or substance) divided by its volume. It is often denoted by the Greek letter "ρ" (rho).

Density is defined as mass per unit volume. The formula for density is:

Density (ρ) = Mass (m) / Volume (V)

Density (ρ) = 78.2 g / 11.4 mL

Now, let's calculate the density:

Density (ρ) = 6.859 g/mL

So, the density of the metal is approximately 6.859 grams per milliliter (g/mL).
