show your work

Answers

Answer 1
Answer:

Answer:

v = 7 m/s

Explanation:

p = m × v

42 = 6 × v

6v = 42

v = 42/6

v = 7 m/s

Mass is measured using _____.scales
a triple beam balance
a mass meter
all of the above

Answers

Answer;

-A triple beam balance

Explanation;

-Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.

-Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.

Mass is measured using scales, a triple beam balance, or a mass meter.

What are scales used for?

Scales are commonly used for everyday measurements, where an object's weight is indirectly measured by the force it exerts on a spring or load cell.

A triple beam balance is a type of mechanical balance that uses a combination of sliding weights to determine mass.

A car drives for 3 hours at 40 mph, and then drives 300 miles at 60 mph. what is the car's average speed, in mph?

Answers

Answer:

52.5 mph

Explanation:

part 1,

speed=40mph

distance= 40×3=120 miles

time= 3 hours

part 2

speed= 60mph

distance= 300 miles

time= 300÷60= 5hours

Average speed= (300+120)÷(5+3) = 52.5mph

Two billion people jump up in the air at the same time with an average velocity of 7.0 m/sec. If the mass of an average person is 60 kilograms and the mass of Earth is 5.98 × 1024 kilograms:
a. What is the total momentum of the two billion people?
b. What is the effect of their action on Earth?

Answers

p=m x v =60 x 7.0= 420
total momentum = 420 x 2,000,000,000=dnt have a calculator
thier effect would shake the earth and kill some organism because they jump up at the same time and they wil probably land the same time .

Explanation:

You view your face in a concave mirror of focal length 20 cm and wish it to be magnified by a factor of 1.5. What should you do?

Answers

Answer:

u = 6.667 cm

Explanation:

given,

Focal length of the concave mirror, f = 20 cm

magnification factor = 1.5  

we know,

M = (-v)/(u)

v is the distance of the image

u is the distance of the object

1.5 = (-v)/(u)

v = -1.5 u

Using mirror formula

(1)/(f)= (1)/(u) + (1)/(v)

(1)/(f)= (1)/(u) - (1)/(1.5u)

(1)/(20)=(1)/(3u)

3u = 20

u = 6.667 cm

distance of the person from the mirror is equal to 6.667 cm.

Which coefficient is needed in front of NaNO3 to balancethe equation Na2S +Zn[NO3]2_ZnS+NaNO#

Answers

So Let's adjust the condition! So to ken how to compose what number of components are on each of the sides from this condition.  The coefficient has to require the apply that the entire aggravate that is denotes we have to decide what number of is on the reactants side so: Na=2 , O=6, N=2 So there is a subscript of 3, so we can now surmise that we can duplicate 2*3=6. So the final answer shall be 2.
