Enzo investigated the effect of different types of fertilizers on the growth of bean plants. He hypothesized that fertilizer B w

ould result in the greatest amount of growth. However, the results showed that the control plants without fertilizer had the greatest growth. Why was Enzo's data still valuable even though it did not support his hypothesis?

Answer:

The answer is "In this information, Enzo will be confident that if any fertilizer is required only for plants".

Explanation:

The Beans plants were members of the group of legumes. Legume flowering plant under which the roots form nodules. These nodules require a specific bacterium called bacteria, which fix nitrogen. Its bacterium transforms nitrogen from the atmosphere into the soil's nitrate. Consequently, for some of its growth, beans do not require fertilizer.

Lots of factors play a role. Firstly if he is presbyopic he won't be able to read without specs at normal reading distances. Many years ago a chap by the name of Donders published a table which shows a linear relationship between age and ability to focus. The ready made reader market relies on his findings to suggest the power you need for reading at different ages. Secondly if he is far sighted (needing correction at distance to see clearly) it will also influence his ability to see close. For example +3.00D distance Rx at an age of 40 years will be very different than the same prescription at age 20 years due to his ability to accommodate. My suggestion is to have comprehensive eye exam to find out what you need at the specific working distance (computer or laptop or book reading all have different reading distances).

The gravitational force between two volleyball players is 3.3x10^-7.
Pepsi [2]

The distance of separation between the two masses is 0.927 m.

<h3>Gravitational force:</h3>

This is the force that exists between two masses in the universe.

To calculate the distance of separation of the masses, we use the formula below.

  • F = GMm/r².............. Equation 1

Where:

  • F = Gravitational force
  • m = First mass
  • M = Second mass
  • G = Universal constant
  • r = distance of seperation.

Make r the subject of the equation.

  • r = √(GMm/F)................... Equation 2

From the question,

Given:

  • F = 3.3×10⁻⁷ N
  • m = 61 kg
  • M = 75 kg
  • G = 6.69×10⁻¹¹ Nm²/kg²

Substitute these values into equation 2

  • r = √(61×75×6.69×10⁻¹¹)/(3.3×10⁻⁷)
  • r = 0.927 m

Hence, The distance of separation between the two masses is 0.927 m

A baseball travelling horizontally at 41 m/s [S] is hit by a baseball bat, causing its velocity to become 47 m/s [N]. The ball i
dmitriy555 [2]

Answer:

46.3\times 10^3 m/s^2

Explanation:

We are given that

Initial velocity of baseball=u=-41m/s

Because final and initial velocity are in opposite direction

Final velocity of baseball=v=47m/s

Time=t=1.9 ms=1.9\times 10^{-3} s

1 ms=10^{-3} s

We have to find the acceleration .

We know that

Acceleration=a=\frac{v-u}{t}

Using the formula

Acceleration=a=\frac{47+41}{1.9\times 10^{-3}}m/s^2

Acceleration=46.3\times 10^3 m/s^2
