A scientific study is repeated by four different groups. Only two groups get the same results. Are the data reproducible?

Answers

Answer 1

Answer: No, one more group must get the same result as the other group. This will make it more reliable and reproducible.

Juan lives 100m away from bill whats juan`s average speed if he reaches bill home in 50 s

Answers

Distance = Speed x Time, we are going to derived our equation.
You can compute for the average speed using the equation: speed = distance ÷ time.
So plugging in our data, it will look like:
Speed = distance / time
= 100 m / 50 s
= 2 m/sec
Juan average speed is 2 m / sec.

2m/sec

While digging in the backyard, you find an old coin. It’s mass is 26.76 g and it’s volume is 3 cm . What is the density?

Answers

Considering the definition of density, the density of the old coin is 8.92 $(g)/(cm^(3) )$ .

It is neccesary to know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance, that is, density is the relationship between the mass of a substance and the volume it occupies.

Mathematically, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=(mass)/(volume)$

In this case, you know:

mass= 26.76 g
volume= 3 cm³

Replacing in the definition of density:

$density=(26.76g)/(3cm^(3) )$

Solving:

density= 8.92 $(g)/(cm^(3) )$

The density of the old coin is 8.92 $(g)/(cm^(3) )$ .

Density = mass/volume

26.76/3 = 8.92

The density is 8.92

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.

Answers

Yes. Earth gets bigger every year. This cumbersome everyday mass accumulation can be charged toward nearly 100 weights of stars penetrating the Earth’s environment per day.

Naturally yes, gravity plus the ever-increasing growing population of living organisms (human beings, animals, bugs, and etc.). Hope this helps!
