Answer:

Momentum must be conserved in the collision.

The steel block must move faster after the collision to preserve momentum.

If the steel block is moving faster it will aso have more kinetic energy.

(Note; If the bullet hits the steel block it will have some momentum in the reverse direction and thus have a greater change in total momtntum than the bullet that becomes imbedded in the wood block)

Star formation is a physical phenomenon where molecular clouds in space need to collapse to generate stars.

Stellar evolution is a process that initiates when a star is formed and ends when it dies (formation of a red giant).

Stars can be generated inside clouds of dust which are dispersed in different types of galaxies in the universe.

Explanation:

Displacement covered by the man calculated by using Pythagoras theorem is 10 km.

Pythagoras theorem states that, for a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the altitude and base sides.

Here,

The Pythagoras Theorem can be written as,

c² = b² + a²

where c is the hypotenuse, b is the base and a is the altitude of the triangle.

An example of application of the Pythagoras theorem is,

A man started walking from his home and covered a distance of 8 km towards the east and then turned right and walked a distance of 6 km towards the south, what is his displacement now from his starting point ?

A line drawn from his current position and his initial point represents the displacement covered by the man.

Let the starting point be A, then he walks to the point B and then he turns right and walks upto the point C.

Drawing a figure including all the data, we get a right angled triangle, ABC. So,

The base of the triangle, BC = 6 km

Altitude of the triangle, AB = 8 km

The displacement of the man = hypotenuse of the triangle

d = AC

According to Pythagoras Theorem,

AC² = BC² + AB²

AC² = 6² + 8² = 100

AC = √100

Therefore, displacement, d = AC = 10 km.

Hence,

Displacement covered by the man calculated by using Pythagoras theorem is 10 km.

Answer: 5.44 m/s

Explanation:

Given:

Mass of cart: 160 kg

Momentum of cart: 870 kg•m/s

[tex]$$Momentum $|\rho|=m \times v$$$\begin{aligned}&870 \ kg\cdot m/s=160 \mathrm{~kg} \times v \\&v=5.44 \mathrm{~m} / \mathrm{s}\end{aligned}$$[/tex]

Answer:

The momentum is defined as :

P=mv

Where m is the mass and v is the velocity. In this case we know the mass is 160 kg and the momentum is 870 kg plugging in this equation above and solving for the velocity we have

870=160V

V=870÷160

V=5.44

Therefore, the velocity of the cart is 5.44 m/s.

Answer:

Explanation:

We know the relation :

We are given that :

Hence, on substituting the values in the equation :

The given information is,

→ Mass = 2 kg

→ Acceleration= 8.3 m/s

→ Force = F (in Newton)

Now we have to find the,

→ Amount of force applied to the object.

Formula we use,

→ F = Mass × Acceleration

Then the amount of force will be,

→ F = Mass × Acceleration

→ F = 2 × 8.3

→ [ F = 16.6 N ]

Hence, the amount of force is 16.6 N.

Explanation:

the compression force is the force generated from compressing an object or substance. When shearing forces are aligned into each other, they are called compression forces.

The compression force is used to power everything from compression brakes to hand tools. The compressive strength of materials and structures is an important engineering consideration.

The compression force can be visualized by placing an object on a spring. When the spring is compressed and then released, the object is ejected into the air.

This is a result of the compression force that is generated from compressing the spring.

This system has a constant velocity, and there is an equilibrium because the tension in the cable, which is pulling up the object, is equal to the weight force, i.e., mg. Where M is a mass, and g is the acceleration caused by gravity, which is pulling down the object.

T = Mg

Tension word becomes from a Latin word meaning “to stretch.” Testing part of the force, Like one type of pull force. All physical objects that are in contact may exert forces on each other.

This contact forces different names based on these types of objects in contact. Where one of the objects exerting the force happens to be a rope, string, chain, or cable we call the force tensions

The given reaction, HCl + NaOH --- NaCl + H₂O is an example of an exothermic reaction. Hence, option A is correct.

In a reaction, the energy released in the form of heat is called an exothermic reaction. In an exothermic reaction, the heat energy is transferred to the surroundings. The chemical equation is Reactant = Product + Energy.

The energy absorbed from the surroundings is called an endothermic reaction. The heat energy taken from the reactants to form a product is called an endothermic reaction. It is described by the chemical equation as Reactant + Energy = Product.

From the given reaction,

HCl + NaOH --- NaCl + H₂O

HCl and NaOH is reactant and NaCl and water is a product. When strong acid (HCl) is mixed with a strong base (NaOH), it gives sodium chloride(NaCl) and water along with heat energy.

When the product is formed from the reactant, heat energy is released. This reaction is also called a Neutralisation reaction. The neutralization reaction are exothermic reaction, that forms chemical bonds by the release of energy.

When water is formed as a product by the release of greater energy than the energy absorbed is called a Neutralization/ exothermic reaction. Hence, the correct option is A) It is exothermic.

The approximate speed of the sound wave traveling through the solid material is 1012m/s.

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

From the wavelength, frequency and speed relation,

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given the data in the question;

To determine the approximate speed of the wave, we substitute our given values into the expression above.

λ = v ÷ f

2.3m = v ÷ 440s⁻¹

v = 2.3m × 440s⁻¹

v = 1012ms⁻¹

v = 1012m/s

Therefore, the approximate speed of the sound wave traveling through the solid material is 1012m/s.
