F=ma therefore m=f/a so the mass is 1000/10=100 Kg

Can someone help me Btw the last one say current

Sliva [168]

Magnitude: Magnitude generally refers to the quantity or distance.

Attraction: A force that makes things move together and stay together.

Repulsive: The feeling of being repelled, as by the thought or presence of something; distaste, repugnance, or aversion.

Current: Current is the rate of flow of electric charge. A potential difference (voltage) across an electrical component is needed to make a current flow through it.

Which of the following is best described as a synthesis reaction? (2 points) 2HgO → 2Hg + O2 AgNO3 + NaCl → AgCl + NaNO3 HCl + N

Shtirlitz [24]

2Na + Cl₂ → 2NaCl

Explanation:

The reaction of sodium metal with chlorine gas to produce sodium chloride is a typical example of synthesis reaction.

Combination or synthesis involves the formation of a single product from two or more reactants.

A + B ⇒ C

In this kind of chemical reaction, a single product is formed or some compounds by the union of elements is notable.

The driving force for this category of chemical reaction is the large and negative heat of formation of the product.

A billiard ball collides with a second identical ball in an elastic head-on collision. What is the kinetic energy of the system

murzikaleks [220]

Answer:

Explanation:

From the question, we were made to understand that the collision between the two billiard balls was an elastic collision. Hence, an elastic collision is one in which the kinetic energy is conserved. Meaning the kinetic energy before the collision is still retained after the collision.

Kinetic energy before collision = kinetic energy after collision

1/2mv^2 = 1/2mv^2

There was no gain nor loss in energy

A golfer gives a ball a maximum initial speed of 51.5 m/s. how far does it go

nata0808 [166]

Answer:

Golf ball will go a maximum of 270.36 meter.

Explanation:

Projectile motion has two types of motion Horizontal and Vertical motion.

Vertical motion:

We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Considering upward vertical motion of projectile.

In this case, Initial velocity = vertical component of velocity = u sin θ, acceleration = acceleration due to gravity = -g $m/s^2$ and final velocity = 0 m/s.

0 = u sin θ - gt

t = u sin θ/g

Total time for vertical motion is two times time taken for upward vertical motion of projectile.

So total travel time of projectile = 2u sin θ/g

Horizontal motion:

We have equation of motion , $s= ut+\frac{1}{2} at^2$ , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

In this case Initial velocity = horizontal component of velocity = u cos θ, acceleration = 0 $m/s^2$ and time taken = 2u sin θ /g

So range of projectile, $R=ucos\theta*\frac{2u sin\theta}{g} = \frac{u^2sin2\theta}{g}$

Now in the given problem

A golfer gives a ball a maximum initial speed of 51.5 m/s. how far does it go

u = 51.5 m/s, for maximum range θ = 45⁰

So maximum distance reached = $\frac{51.5^2sin(2*45)}{9.81}=270.36 meter$

So it will go a maximum of 270.36 meter.
