Answer:

[tex]45m[/tex]

Explanation:

Let [tex]V_0[/tex] be the horizontal speed of the keys and D be the horizontal distance covered by the keys.

[tex]V_0= 8.0 \frac ms[/tex]

[tex]D= 28 m[/tex]

The initial velocity in the vertical direction is [tex]0[/tex].

Let [tex]g[/tex] be the acceleration due to gravity, which always acts vertically downwards, so, it will not change the horizontal direction of the speed, i.e. [tex]V_0[/tex] will remain constant throughout the projectile motion.

Let [tex]t[/tex] be the total time of flight in seconds. So,

[tex]D= V_0t[/tex]

[tex]\Rightarrow 28=8t[/tex]

[tex]\Rightarrow t=3 s \; \cdots (i)[/tex]

Let [tex]H[/tex] be the hight of the cliff.

Now, from the equation of motion

[tex]s=ut+\frac 1 2 at^2\;\cdots(ii)[/tex]

Where is the displacement is the direction of force, is the initial velocity in the direction of force,   is the constant acceleration due to force and is the time of flight.

Here, , and  (negative sign is for taking the sigh convention positive in the direction as shown in the figure.)

From equation (ii)

[tex]-H=0\times t + \frac 1 2 (-g)t^2[/tex]

[tex]\Rightarrow H= \frac 1 2 gt^2[/tex]

Take [tex]g= 10 \frac m{s^2}[/tex] and put the value of [tex]t[/tex] from equation (i), we have

[tex]H=\frac 1 2 \times 10\times 3^2[/tex]

[tex]\Rightarrow H= 45 m[/tex].

Hence, the height of the cliff was [tex]45 m[/tex].

Answer:

sorry im only in fifth grade

Explanation:

Answer:

9.09m/s

Explanation:

Speed = Distance/Time

Distance = 495km

Time = 4 hr 30 min = 4 hr 1/2hr = 4.5 hr

Therefore, Speed = 495/4.5 = 110km/h

Now to convert km/h to m/s

110 x 1000/ 110 x 110

110 cancels out each other, we are now left with

1000/110 = 9.09m/s

Weight = (mass) x (gravitational acceleration where the mass is)

Weight = (1360 kg) x (9.8 m/s²)

Weight = 13,328  kg-m/s²

That's 13,328 Newtons

Given:-

To Find: Weight (W).

We know,

W = mg

where,

Thus,

W = (1360 kg)(9.8 m/s²)

→ W = 13,328 N (D)

Answer:

The overall force pushing on the block is 26.63 N in the direction of N 34° E

Explanation:

Given;

force going north, F₁ = 15 N

force going east, F₂ = 22 N

The resultant of the two forces is the hypotenuse side of the right angled triangle formed by the two forces.

Let the magnitude of the resultant force = F

F² = F₁² + F₂²

F = √(F₁² + F₂²)

F = √(15² + 22²)

F = 26.63 N

The direction of the force is the angle between the resultant force and the horizontal force.

tan θ = 15 / 22

tan θ = 0.6818

θ = tan⁻¹ ( 0.6818)

θ = 34°

Therefore, the overall force pushing on the block is 26.63 N in the direction of N 34° E

Answer:

liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

The atoms of solids and liquids are different from each other in many ways as discussed below.

We have a solid and a liquid.

We have to describe how the atoms of a solid differ from the atoms of a liquid.

An Atom smallest unit into which matter can be divided without the release of electrically charged particles.

According to the question, the following differences exists between the atoms of solids and liquids -

Hence, it can be seen that the atoms of solids and liquids are quite different from each other.

Answer:

Horizontal Component = 129.9 km/h

Vertical Component = 75 km/h

Explanation:

When a vector is resolved on the x-axis and the y-axis, the components so formed are called its rectangular components. The component along y-axis is called the vertical component and the component along x-axis is called horizontal component. These components can be given by following formulae:

Horizontal Component = v Cos θ

Vertical Component = v Sin θ

where,

v = velocity = 150 km/h

θ =  angle = 30°

Therefore,

Horizontal Component = (150 km/h)(Cos 30°)

Horizontal Component = 129.9 km/h

Vertical Component = (150 km/h)(Sin 30°)

Vertical Component = 75 km/h

Answer: The anser is C

Explanation:

It is the same if no external forces are added.

Based on the principle of conservation of linear momentum, the final total momentum of both carts compared to the initial total momentum is the same if no external forces are added.

The given information;

According to the principle of conservation of linear momentum, the total momentum before collision is equal to the total momentum after collision.

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

where;

Thus, based on this principle (conservation of linear momentum), the final total momentum of both carts compared to the initial total momentum is the same if no external forces are added.

Answer:

Key Fob.

Explanation:

On the 5th of September, 1977, the National Aeronautics and Space Administration (NASA) launched a spacecraft known as "Voyager 1" to study and explore the outer planets of the solar system.

Additionally, two voyager spacecraft were built for the above mentioned study and exploration exercise; Voyager 1 and Voyager 2. Voyager 2 was actually the first spacecraft while Voyager 1 was launched sixteen (16) days after and was faster.

According to Rich Terrile, the technology they had in the 70's was similar to a modern day Key Fob that could fit in our pocket because the processing power of the computer chip found in a Key Fob was comparable to the much larger voyager probe (Voyager 1 and Voyager 2) of the 70's, that was tagged an artificial brain.

This ultimately implies that, the computer chip found in a car Key Fob is more powerful and sophisticated than the Voyager probe, even though the Key Fob is smaller but having the same amount of memory.

Answer:

Free-fall is defined as the movement where the only force acting on an object is the gravitational force.

By the second Newton's law, we have that:

F = m*a

Where F = Force, m = mass, a = acceleration.

We can write this as:

a = F/m

And the gravitational force can be written as:

F = (G*M/r^2)*m

Where G is the gravitational constant, M is the mass of the Earth in this case, and r is the distance between both objects (the center of the Earth and the free-falling object)

As the radius of the Earth is really big, the term inside the parentheses is almost constant in the region of interest, then we can write:

G*M/r^2 ≈ g

And the gravitational force is:

F = g*m

And by the second Newton's law we had:

a = F/m = (g*m)/m = g

a = g

Then the acceleration does not depend on the mass of the object.

Then the thing that is common among the free-falling objects is the vertical acceleration.

Explanation:

This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.
