Answer:

Nowadays most of our works are being done through different types of energy which are non-renewable. People are wasting lot of energy (hydel, dolar etc.) due to which in future we can face energy crisis.

Speed = 540 miles/hr

= (540 x 1.609) km/hr

= 868.86 km/hr

Distance = Speed x Time

= 868.86 x 1 / 2

= 434.43 km

Answer:

A. wind blows from the land toward the sea.

B. that this happens because the land cools faster than the sea, and, as a result, the air over land cools faster, which creates an area of higher pressure on land and lower pressure over the sea.

Answer: v = 0.6 m/s

Explanation: Momentum Conservation Principle states that for a collision between two objects in an isolated system, the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.

Momentum is calculated as Q = m.v

For the piñata problem:

[tex]Q_{i}=Q_{f}[/tex]

[tex]m_{p}v_{p}_{i}+m_{s}v_{s}_{i}=m_{p}v_{p}_{f}+m_{s}v_{s}_{f}[/tex]

Before the collision, the piñata is not moving, so [tex]v_{p}_{i}=0[/tex].

After the collision, the stick stops, so [tex]v_{s}_{f}=0[/tex].

Rearraging, we have:

[tex]m_{s}v_{s}_{i}=m_{p}v_{p}_{f}[/tex]

[tex]v_{p}_{f}=\frac{m_{s}v_{s}_{i}}{m_{p}}[/tex]

Substituting:

[tex]v_{p}_{f}=\frac{(0.54)(4.8)}{(4.4)}[/tex]

[tex]v_{p}_{f}=[/tex] 0.6

Immediately after being cracked by the stick, the piñata has a swing speed of 0.6 m/s.

Explanation:

Given that,

The mass of an object, m = 1 kg

The mass of Earth, [tex]m_e=6\times 10^{22}\ kg[/tex]

The mass of Moon, [tex]m_m=7.4\times 10^{22}\ kg[/tex]

The distance between the two bodies, [tex]d=3.8\times 10^5\ km =3.8\times 10^8\ m[/tex]

The gravitational force between the object and the earth,

[tex]F=\dfrac{Gmm_e}{d^2}\\\\=\dfrac{6.67\times 10^{-11}\times 1\times 6\times 10^{22}}{(3.8\times 10^8)^2}\\\\=2.77\times 10^{-5}\ N[/tex]

The gravitational force between the object and the Moon,

[tex]F=\dfrac{Gmm_m}{d^2}\\\\=\dfrac{6.67\times 10^{-11}\times 1\times 7.4\times 10^{22}}{(3.8\times 10^8)^2}\\\\=3.41\times 10^{-5}\ N[/tex]

Hence, this is the required solution.

Answer:

If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. ... Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.

Explanation:

If the motion of an object changes, the net force on the object is greater than zero or the forces acting on the object is unbalanced.

According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object. The object will move in the direction of the applied force.

When the net force on an object is zero, the object will be remain at rest.

However, when the net force on object is greater than zero, the object will move in the direction of the greater force.

Thus, we can conclude that if the motion of an object changes, the net force on the object is greater than zero or the forces acting on the object is unbalanced.

non uniform speed

The speed, the following scenario depicts is non uniform speed. According to the values given in the question, average speed can be 2.083 m/s.

When the speed is changing with respect to time, the speed is called as the non uniform motion.

Jennifer is traveling on her bike to the park. The speed is firstly slow, then increases. The distance traveled is 1000 m and time taken is 8 min, so the average speed will be

average speed = total distance / total time taken

average speed = 1000 /(8x 60)

average speed = 2.083 m/s

Thus, the speed, the following scenario depicts is non uniform speed. The average speed is 2.083 m/s.

Answer:

Centripetal acceleration = 8m/s²

Explanation:

Given the following data;

Radius, r = 2m

Velocity = 4m/s

To find the centripetal acceleration;

Centripetal acceleration = V²/r

Substituting into the equation, we have;

Centripetal acceleration = 4²/2

Centripetal acceleration = 16/2

Centripetal acceleration = 8m/s²

Therefore, the dog's centripetal acceleration is 8 meters per seconds square.
