Answers

Answer 1

Answer:

c

Explanation:

pls give brainliest have a great day

Answer 2

TDS and ppm are common units used to measure the quantity of substance in the water, therefore the correct answer is option A.

What is a unit of measurement?

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

Common units used to measure the amount of material in water are TDS and part per million.

As given in the problem we have to find out for what measurement, the units TDS (Total dissolved solid )and ppm (parts per million) are used.

The total dissolved solid and parts per million are used to measure the amount of substance present in the water, therefore the correct answer is option A.

s = s₀ + v₀t + ½at²

vertical analysis with floor level as origin

0 = 1.2 + 5t + ½(-9.8)t²

0 = 1.2 + 5t - 4.9t²

t = (-5 - √(5² - 4(-4.9)(1.2))) / (2(-4.9))

t = 1.22 s is the flight time

A 10-cm-long archerfish begins such a leap with its body vertical in the water, using its fins and undulating its body to propel itself sharply upward. Its acceleration steadily decreases as it leaves the water because less of its body and fewer of its fins are in contact with the water.

With what speed does the fish leave the water?
What height above the water does it reach?

Answers

Answer:

Explanation:

Velocity will be equal to the area under the curve of the acceleration-time plot.

v = ½(45)(0.075) = 1.6875

If a 2 kg block of aluminium (SHC: 921 J/kg°C) is heated from 20°C to 40°C, how much energy was transferred to it?

Answers

H = mc∆T

where, H=heat energy

c = SHC

H = 2*921*(40-20)

H = 36840J

H = 36.84KJ

The energy transferred to it is 36.84KJ

The energy transferred to aluminum from 20°C to 40 °C is equal to 36840 J.

What is the specific heat capacity?

The specific heat capacity can be described as the quantity of heat required to increase the temperature of 1 unit of substance by one degree Celsius. The specific heat capacity of the substance depends upon the nature of the substance.

The mathematical equation is used to calculate the specific heat is equal to:

[tex]Q = m\times C\times \triangle T[/tex]

Given, the mass of the aluminum block, m = 2 Kg

The initial temperature of aluminum, T₁ = 20 °C

The final temperature of the aluminum, T₂ = 40 °C

The specific heat capacity of aluminum, C = 921 J/kg°C

The energy transferred to the aluminum block:

Q = 2 × 921 × (40-20)

Q = 36840 J

Therefore, the energy transferred to aluminum from 20°C to 40°C is  36840 J.

One train (22,680 kg) moving east at 170 km/h collides with a car (1,200 kg) that was moving north at 5 km/h. They get attached to each other, moving in the direction of the train. What is the final velocity of the objects and the type of collision? If the collision happened in 1.2X10-3 seconds, what was the force? How much kinetic energy was lost?

Answers

The final velocity of the objects is 229.82km/hrSince energy was lost after the collision, the type of collision that occurs is an elastic collision.The required force is 1,090,918,000NThe amount of Kinetic energy lost is 12,401,976.656Joules

According to the law of collision'

m1u1 + m2u2 = (m1+m2)v

Given the following:

m1 = 22,680kg

u1 =170km/h

m2 = 1200kg

u2 = 5km/hr

Get the final velocity "v"

22680(170) + 1200(5) = (22680 + 1200)v

3855600 + 6000 = 12880v

3,861,600 = 12880v

v = 3,861,600/12,880

v = 229.82km/hr

Hence the final velocity of the objects is 229.82km/hr

Since energy was lost after the collision, the type of collision that occurs is an elastic collision.

According to Newton's second law, the formula for calculating the force is expressed as;

F = ma

F = m(v-u)/t

F = 22680+1200(229.82-175)/t

Ft = 23880(54.82)

F = 1,309,101.6/0.0012

F = 1,090,918,000N

Hence the required force is 1,090,918,000N

KE lost = Kinetic energy after collision - Kinetic energy before collision

Kinetic energy after collision = 1/2 * 12880 * 229.82²

Kinetic energy after collision = 340,142,976.656 Jolues

Kinetic energy before collision = 1/2 * 22680(170)²+ 1/2*1200(5)²

Kinetic energy before collision = 327,726,000 + 15000

Kinetic energy before collision = 327,741,000

Kinetic energy lost = 340,142,976.656 - 327,741,000 =  12,401,976.656Joules

B.Which hits first depends on the weather & temperature of the air.

C.The 200 g gold coin hits the ground first

D.The 10 g dime hits the ground first

Answers

Answer:

Explanation:

The both hit the ground at the same time. There is no air resistance and that includes the factors brought up in B.

C and D are both eliminated. If you dropped an 800 kg honda Fit it would hit the ground at the same time as the two coins. When you look at the formulas used to derive time, they look like

d = vi * t + 1/2 a* t^2

vi = 0

the distance to fell is the same for all three masses.

a is the same for all 3 masses.

So when you solve for t, there is no mention of the mass of the object falling. Therefore t is dependent only on the height.

A 0.038-kg bullet enters a 3.2-kg watermelon and embeds itself in the melon. The melon is immediately set into motion with a speed of 3.82 m/s. The bullet remains lodged inside the melon. What was the entry speed of the bullet (m/s)?

Answers

Hi there!

This is an example of a perfectly inelastic collection, so:

mb = mass of bullet

vb = velocity of bullet

mw = mass of watermelon

v = velocity final

mbvb = (mb + mw)v

Rearrange to solve for the velocity of the bullet:

vb = (mb + mw)v/mb

Plug in values:

vb = (0.038 + 3.2)(3.82)/(0.038) = 325.504 m/s

Hi there!

On the object, we know that there are two forces working on the object:

-Force due to gravity (Mg)

-Force due to air resistance

Let the positive direction of the force be downwards (direction of the acceleration)

We can write the summation of forces as:

∑F = Mg - Fa

Plug in values. Let g ≈ 10 m/s²

∑F = 30(10) - 50 = 250N

Find the acceleration using the formula:
