The answer is mushrooms are considered to be decomposers. Mushrooms are considered to be a fungi, which means that they create their own food by decomposing organisms, they also absorb nutrients from the organism they absorb. Mushrooms releases enzymes for them to be able to decompose and absorb nutrients from an organism.

What do astronomers mean when they say that the sun makes energy by hydrogen burning?

ratelena [41]

It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. What astronomers mean when they say that the sun makes energy by hydrogen burning is that, the Sun is fusing hydrogen into helium and releasing energy. Hope this helps.

From the edge of a rooftop, you toss a green ball upward with an initial velocity of 10 m/s and a blue ball downwards with the s

Ira Lisetskai [31]

Answer:

c.The two balls will have the same speed.

Explanation:

When two balls green and blue both are moving with initial velocity 10m/s.

The green ball has been tossed upward and blue ball downwards.

Air resistance is negligible means there is no force which oppose the motion of balls.

When blue balls has been tossed downward then the blue ball will move under the gravity.

When green fall downward then the ball falls under the gravity because there is no air resistance.

Therefore, both balls move with acceleration due to gravity when they wil reach at ground.

Therefore, the velocity of both balls are same.

Hence, the two balls will have the same speed.

Option c is true.

The following arbitrary measurements are made and the errors sited are the aximum errors A = 15.21 +0.01, B = 10.82 +0.05, C = 1

Molodets [167]

Maximum error in the result of the sum of measurement is equal to the sum absolute error of the individual observed measurements

(a) The maximum error in D is 0.09

(b) The standard error in D is approximately 0.034

The procedure for arriving at the above values is as follows;

The given measurements and the sited errors are;

A = 15.21 + 0.01

B = 10.82 + 0.05

C = 11.00 + 0.03

D = A + B + C

(a) Required parameter;

To calculate the maximum error in D

The equation for the propagation of error in addition is presented as follows;

Given that we have;

x = a + b

Therefore;

x + ±Δx = (a ± Δa) + (b ± Δb) = a + b ± (Δa + Δb)

∴ Δx = Δa + Δb

From the above formula, we have;

Where;

D = A + B + C

The maximum error in D = The sum of the maximum error in A, B, C

∴ The maximum error in D = 0.01 + 0.05 + 0.03 = 0.09

(b) Required parameter:

To find the standard error in D

The standard error is the sampling distribution's standard deviation, SD

Variance = SD²

The combined variance, SD² = The sum of the squares of individual standard deviations

Given that the standard errors represents the standard deviation, we get;

The combined variance, SD² = 0.01² + 0.05² + 0.03²

The combined variance, SD = √(0.01² + 0.05² + 0.03²) = 0.059

$Standard \ error = \dfrac{SD}{\sqrt{n} }$

Where n = 3, for the three measurement, we get;

$Standard \ error = \dfrac{\sqrt{0.01^2 + 0.05^2 + 0.03^2} }{\sqrt{3} } \approx 0.034$

The standard error in D is approximately 0.034

Ted wants to hang a wall clock on the wall by using a string. If the mass of the wall clock is 0.250 kilograms, what should be t

Ahat [919]

The clock is pulling the force towards earth's center because of gravity.
That force is equal to:
F = m*g where g is gravitational acceleration.

We will take that g = 9.81m/s^2

Now:
F = 0.25 * 9.81 = 2.4525 N

The string needs to sustain that force, therefore minimum Force that string has to be able to sustain is:
2.4525 N
