explain why a high speed collision between two cars would cause more damage than a low speed collision between the same two cars?

Answers

Answer 1

Answer:

Significant transfer of kinetic energy and momentum in high-speed collision causes more damage than low-speed collision.

From the laws of momentum and kinetic energy, a collision between two cars at a high speed would result in more damage than a collision between the same two cars at a moderate speed.

Momentum: An object's momentum is calculated by multiplying its mass by its velocity. The momentum of both cars is a crucial element in a collision. When two cars meet quickly, they have more momentum, which increases the amount of motion and force that is applied to the impact. The two cars' combined momentum increases the force of the collision.

Kinetic Energy: The energy of motion that an object possesses as a result of its mass and velocity. An object's kinetic energy is inversely related to its square of velocity. In comparison to a low-speed accident between the same two cars, the kinetic energy involved in a high-speed collision is substantially more.

A significant quantity of kinetic energy and momentum are transferred to the point of impact when two cars crash at high speed.

In contrast, kinetic energy and momentum are less engaged in low-speed collisions, which leads to less force being applied to the cars and their occupants.

Hence, due to significant transfer of kinetic energy and momentum in high-speed collision causes more damage than low-speed collision.

Answer 2

Answer: I've would cause more damage, because there is nore momentum and input force equals output force and the momentum is transferred between the two cars more so than if they had a lower velocity

A trumpet creates a sound wave that has a wave speed of 350m/s and a wavelength of 0.8 m . What is the frequency of the sound wave

Answers

Answer:

The frequency of sound wave created by trumpet is 437.5Hz

Explanation:

Given

the speed of sound wave = 350 m $s^(-1)$

the wavelength of sound wave = 0.8 m

the frequency of sound wave = ?

All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:

v = fλ, where

v is speed of the wave

f is frequency of the wave

λ is wavelength of the wave

therefore frequency of sound wave is given by

f = v/λ

= 350m $s^(-1)$ /0.8m

= 437.5 $s^(-1)$

= 437.5Hz (since 1 $s^(-1)$ = 1 Hz (Hertz)

Hence the frequency of sound wave created by trumpet is 437.5Hz

Answer:

The frequency of sound wave created by trumpet is 437.5Hz

Explanation:

Given

the speed of sound wave = 350 m

the wavelength of sound wave = 0.8 m

the frequency of sound wave = ?

All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:

v = fλ, where

v is speed of the wave

f is frequency of the wave

λ is wavelength of the wave

therefore frequency of sound wave is given by

f = v/λ

= 350m/0.8m

= 437.5

= 437.5Hz (since 1 = 1 Hz (Hertz)

Hence the frequency of sound wave created by trumpet is 437.5Hz

Vince is baking a cake. He pours flour and sugar into an empty bowl. The substance in the bowl is a(n) __________.a)atom.
b)element
c)mixture.
d)compound.

Answers

Answer: c) mixture.

Explanation:

An atom is the smallest entity of any substance which consists of subatomic particles called as neutrons, protons and electrons.

An element is a pure substance which is composed of atoms of similar elements. Example: $H_2$

Mixture is formed when atoms of similar or different elements are mixed in no fixed ratio without any chemical combination.

A compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: $H_2O$

It is 'C', a mixture, because flour and sugar are both a compound.
