1. they both act on an object in free fall

Explanation:

2. both help determine how fast the object will accelerate

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:

122.5 meters

Explanation:

We have the third equation of motion:

[tex]\boxed{\mathsf{v^2=u^2+2aS}}[/tex]

Here, the particle is a flare.

It's initial velocity is 49 m/ s and the final will be zero, that's 'cause the particle comes to a standstill upon reaching its maximum, in case of motion under gravity.

a will be the acceleration due to gravity = 9.8 m/ s²

So, here are the terms we've got for the third eqn. of motion:

Now, the term we've got to find out is the height reached by the flare, i. e., S.

=> v² = u² + 2aS

=> (0)² = (49)² + 2×(-9.8)×S

=> 0 = 49×49 - 2×9.8×S

=> 2×9.8×S = 49×49

[tex]\implies \mathsf{S=\frac{49\times 49}{2\times9.8} }[/tex]

=> S = [tex]\frac{245}{2}[/tex]

And, S is the maximum height the flare covers, so the answer is 122. 5 meters

[tex]\\ \sf\longmapsto 5.5t=1.2t^2[/tex]

[tex]\\ \sf\longmapsto t^2=\dfrac{5.5}{1.2}[/tex]

[tex]\\ \sf\longmapsto t^2=4.58[/tex]

[tex]\\ \sf\longmapsto t=\sqrt{4.58}[/tex]

[tex]\\ \sf\longmapsto t=2.1[/tex]

The other force that must be acting on the duck is upthrust of 10 N.

The given parameters;

When the weight of the object is equal to the upthrust, the apparent weight will be zero and the object will float in the liquid. This is known as principle of floatation.

Since the given weight of the rubber duck is 10 N, then the upthrust on the duck will be 10 N to enable the duck float on the water.

Thus, the other force acting on the duck is upthrust of 10 N.

The ball is traveling at a steady speed until it hits an unbalanced force and changes direction.

Explanation:

The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.

Thus, An unbalanced external force acts upon an item, Newton's first law of motion, often known as the law of inertia, asserts that an object at rest will remain at rest and an object in motion will continue to move in the same direction and at the same pace.

When a baseball is struck with a bat, it is originally at rest or moving steadily forward.

The ball experiences an imbalanced force when it is struck by the bat, altering its direction and speed. The bat's application of external force is what causes this shift in motion.

Thus, The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.

Answer:

There is 18

Explanation:

The combination of a particle's mass and velocity produces momentum. Momentum is a vector quantity that has both magnitude and direction. The force exerted on a particle is equated to the time rate of change of momentum by Isaac Newton's second equation of motion.

First law of Newton : According to Newton's first law of motion, if a body is at rest or moving in a straight path at a constant speed, it will stay in that state or continue to move in that direction unless it is acted upon by an outside force.

Second law of Newton : According to Newton's second rule of motion, a body's rate of momentum change is inversely proportional to the force acting on it, and momentum changes occur in the direction of the net applied force.

Third law of Newton : Newton's third law of motion states that there is always an equal and opposite reaction to every action.

In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this.

A push or pull that an object experiences as a result of its interactions with its environment is known as a force.

Dust and smoke rising in the atmosphere as a result of an asteroid impact hinder sunlight from reaching our planet, resulting in a decrease in global temperature. Many living beings could die as a result of this incident. A small city might be destroyed if an asteroid the size of an apartment strikes Earth. A 20-story building-sized asteroid might wipe out a small nation if it were to strike Earth.

Answer:

C

Explanation:

Newton's first Law of Motion is also known as law of inertia, which states that "an object at rest remains at rest, and an object that is moving will continue to move straight and with constant velocity, if and only if there is no net force acting on that object". As such, the correct option should be C.

Option A is Newton's third Law of Motion.

Option B is Newton's second Law of Motion

Option D is Newton's Law of Universal Gravity

Legend has it that a young Isaac Newton was sitting under an apple tree when he was bonked on the head by a falling piece of fruit, a 17th-century “aha moment” that prompted him to suddenly come up with his law of gravity.

Answer:

I = 1575 / 5000 = 31.5 % interest on investment

(1 + i)^18 = 1.315      where i interest is earned per year

One can use logs or

1 + i = 1.315^1/18  = 1.0153

So the annual interest rate is .0153   or 1.53%

Or

5000 (1 + i)^18 = 6575

(1 + i)^18 = 1.315

18 log (1 + i) =  log 1.315

log (1 + i) =  .006607

1 + i = 1.0153

i = .0153 = 1.53%

Answer:

0.00278 km/sec2 or 36,000 km/hr2 .

Explanation:

We have that the expression for the magnitude of the horizontal force F is

[tex]F=(m_1+m_2)gtan\phi[/tex]

From the question we are told

find an expression for the magnitude of the horizontal force f in the figure for which m1 does not slip either up or down along the wedge. all surfaces are friction-less.

Generally the equation for Normal force   is mathematically given as

[tex]N=\frac{n_2g}{cos\pji}[/tex]

Where

a signifies acceleration

[tex]Nsin\phi=m_2a[/tex]

Therefore

Equating above equations

[tex]a=\frac{Nsin\phi}{m^2}\\\\a=gtan\ph[/tex]i

Generally the equation for Force on wedge   is mathematically given as

[tex]F=m_1a+Nsin\phi[/tex]

[tex]F=(m_1+m_2)gtan\phi[/tex]

Therefore

The expression for the magnitude of the horizontal force F is

[tex]F=(m_1+m_2)gtan\phi[/tex]
