She can use the information of redshift of a celestial body is to find the age and distance of the object.

'Red shift' is a critical idea for astronomers. The frequency of the light is increased, so the light is observed as moving towards the red side of the range.

Tabitha knows the redshift value of a particular celestial object. She uses this information to observe the consequence of the redshift.

The velocity of the 2x10^4 kg car just before the collision is 0 m/s.

When two bodies of different masses move together each other and have head on collision, they travel to same or different direction after collision.

The external force is not acting here, so the initial momentum is equal to the final momentum. For inelastic collision, final velocity is the common velocity for both the bodies.

m₁u₁ +m₂u₂ =(m₁ +m₂) v

Substitute the values for m₁ = 1.5 x 10^4 kg, m₂ =2 x 10^4 kg and u₁ =7 m/s, the final velocity is 3m/s/

1.5 x 10^4 x 7+2 x 10^4 x u₂ = (1.5 x 10^4 + 2 x 10^4) x 3

u₂  = 0 m/s

So, the car with mass  2x10^4 kg is stationary.

Sustainability is the most appropriate as it means meeting our own needs without compromising the ability of future generations to meet their own needs.

Given that, 1 Liter equals 1.0567 quartz and 1 quartz equals 32 oz, the volume 1.00 oz equals 0.02957 L.

Given that;

First, we convert 1.00 oz to qt

32 oz = 1 qt

1.00 oz = x

x = 1.00 / 32

x = 0.03125 qt

Now, we convert 0.03125 qt to liter

1.0567 qt = 1 L

0.03125 qt = x

x = 0.03125 / 1.0567

x = 0.02957 L

C. The initial temperature of the water that would be enough to just barely melt all of the ice is 20.57 °C.

The specific heat is the amount of heat required to change the temperature by 1°C. It is denoted by C.

Heat lost or gained is represented as

Q = m C ΔT

Given, Mass of ice, mice = 9x10⁻² kg, Mass of water, mw =0.35 kg, T = 13 °C

A. If ice is in excess, final water temperature will be 0°C.

B. Specific heat of water Cp = 1000 cal/kg°C

Latent heat of ice L = 80 kcal/kg

In that case, heat lost by water =Heat gain by ice

Q = mCp x dT = mL

0.35 x 1000 x 13 = m x 80 x 1000

m = 0.0569 kg of ice.

The gram of ice remaining = 0.09 - 0.0569

                                             = 0.0331 gram of ice.

Thus,  the amount of ice remaining is 0.0331 g

C. Heat required to melt 90 gram of ice,  Q  mL

Q = 90 x 80 = 7200 cal.

If the initial temperature of water needed = T,

Answer:

Yes

Explanation:

Average velocity is the ratio of total displacement and time taken for that displacement:

[tex]average \space\ velocity = \frac{displacement}{time}[/tex]

This means if displacement is zero, then average velocity will also be zero.

Displacement is zero when an object moves some distance in one direction, and then moves the same distance but in the opposite direction.

∴ As it is possible for displacement to be zero, it is also possible for average velocity to be zero.

The given statement is true ultrasonic cleaners are based on the same principle as echolocation in bats and some other animals.

A physiological method for identifying far-off or unseen items (like prey) using sound waves that the objects reflect back to the source, such as a bat.

High-frequency sound waves are used in ultrasonic cleaning to scour clean objects that are submerged using liquid as a medium.

The cavitation of the solution's molecules is brought on by the high-frequency sound waves, which are generally 40 kHz in frequency.

Although bats have developed an advanced kind of echolocation that allows them to travel and find food in the dark, they have vision that is comparable to that of humans.

Bats use high frequency sound pulses emitted through their mouth or nose and listen for the echoes to achieve echolocation.

It is accurate to say that ultrasonic cleaners work on the same principles as creatures like bats and certain others that use echolocation.
