Copper has a specific heat of 0.385 j. A piece of copper absorbs 5000 J of energy and undergoes a temperature change from 100 Celsius to 200 degrees Celsius. What is the mass of the piece of copper?

Answers

The mass of the piece of copper will be 130 kg. In the International System of Units (SI), the kilogram is the unit of mass.

What is mass?

Mass is a numerical measure of inertia, which is a basic feature of all matter. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force.

The energy absorbed as;

$\rm \triangle E = mC \triangle t \n\n m = (\triangle E )/(mC) \n\n m = (5000 )/(0.385 (200-100)) \n\n m=130 \ kg$

Hence, the mass of the piece of copper will be 130 kg.

Sachi wants to throw a water balloon to knock over a target and win a prize. The target will only fall over if it is hit with a force of 0.035 N. The water balloon has a mass of 11.4 grams. How fast will Sachi have to make the water balloon accelerate to hit the target with enough force and win the prize?Round the answer to the nearest one tenth m/s2.
The water balloon must accelerate m/s2.

Answers

Answer:

3.1 m/s²

Explanation:

Given:

Mass of the balloon (m) = 11.4 g = 0.0114 kg ( 1 kg = 1000 g)

Force acting on the balloon (F) = 0.035 N

Acceleration with which the balloon must be hit (a) = ?

Now, we know that, from Newton's second law, net force acting on an object is equal to the product of its mass and acceleration.

Therefore, framing in equation form, we have:

$F=ma$

Rewriting in terms of acceleration 'a', we get:

$a=(F)/(m)$

Now, substitute the given values and solve for 'a'. This gives,

$a=(0.035\ N)/(0.0114\ kg)\n\na=3.07\approx 3.1\ m/s^2(Nearest\ tenth)$

Therefore, the acceleration of the water balloon to reach the target must be equal to 3.1 m/s².

When atoms form a bond, it is usually because each atom acquires a more stable arrangement of electrons in its electron shells. What is the best description of this arrangement of electrons?

A.
All shells have the same number of electrons.

B.
The inner shells are empty.

C.
The outer shell is completely full.

D.
All shells are half full.

Answers

C. Usually when an atom loses or gains an electron, it is because it is trying to satisfy the Octet Rule. The Octet Rule states that an atom is at its stablest when it has 8 valence electrons (two in helium's case)

If you look on the periodic table, elements on the left (Alkaline Metals) are the most reactive because they only have one valence electron (or electron in the outer shell). Elements on the right (Noble Gases) are the least reactive because they have a full outer shell of 8 valence electrons.

Later on you will find that as stability decreases as you go down the periodic table but that is a discussion for a different time.

the answer is C.The outer shell is completely full.

A car traveling with constant speed travels 150 km in 7200 s. What is the speed of the car?Express the speed to two significant figures and include the appropriate units.

Answers

The speed of the car is 75 km/h

Further explanation

These are the formulas that we have to remember before solving the problem.

Speed is the rate of change of distance.

$\large { \boxed {v = (d)/(t)}}$

v = speed ( m/s )

d = distance ( m )

t = time ( s )

Acceleration is the rate of change of velocity.

$\large { \boxed {a = (\Delta v)/(t)}}$

a = acceleration ( m/s² )

Δv = change in speed ( m/s )

t = time ( s )

Let us now tackle the problem!

Given:

distance = d = 150 km

time taken = t = 7200 s = 2 hours

Unknown:

velocity = v = ?

Solution:

$v = (d)/(t)$

$v = (150)/(2)$

$\large {\boxed {v = 75~km/h} }$

The acceleration of the car is 0 m/s² because it travels with constant speed.

We could also plot the distance vs time graph as shown in the attachment.

Grade: Middle School

Subject: Physics

Chapter: Kinematics

Keywords: indycar top speed of a fastest police car has ever gone

Final answer:

The car's speed is 75 km/hour, as determined by dividing the total distance travelled (150 km) by the total time taken (2 hours).

Explanation:

To answer this question, we use the

formula for speed

, which is distance traveled divided by the time taken. Here, the distance travelled by the car is 150 km and the time taken is 7200 s (which is equal to 2 hours). Therefore, the speed will be 150 km divided by 2 hours, resulting in a speed of

75 km/hour

, stated to the correct number of significant figures.

What is an example of a compressional wave?

Answers

Sound is an illustration of a compressionalwave. Mechanical waves like sound waves need a medium to travel through, such air, water, or solids.

A sound wave undergoes compressions and rarefactions as it passes through a medium.

Particles in the medium move parallel to the wave's propagation direction during a compressional wave.

When particles are close to one another, compression regions arise in the case of sound waves, creating high-pressure zones.

Following these compressed zones are rarefactions, when the particles are dispersed and low-pressure areas develop.

Thus, sound is an example of a compressional wave.

#SPJ6

Answer:

The wave front expanding out from an explosion is possibly the most dynamic example of a compressional wave. And a pulse of compressed air can transfer a LOT of energy. ... For a literal "compression wave" visualize accelerating a boat across the water, compressing the water it encounters into a "bow wave".
