Appropriate Question:-

The output for a 60kg woman who runs up a 3m high flight of stairs in 3.5 sec.starting from rest but having a final speed of 2 m/s.

Given:-

Mass of woman=m=60kg.

Height=h=3m

Time=t=3.5secs.

To find :-

Here we want to calculate the output for a woman

Here first we should calculate work done first.

work \: done = mghworkdone=mgh

Applying the values,

work \: done = 10 \times 60 \times 3workdone=10×60×3

Work done= 1800Joule.

Now , lets calculate power,

power = \frac{workdone}{time \: taken} power=

timetaken

workdone

Now,

Applying the values ,

power = \frac{1800}{3.5} power=

3.5

1800

Power =514.2857 watt.

Hope it helps u mate .

What is one difference between primary and secondary succession? Primary succession can start from bare rock; secondary succession starts from organic soils. Primary succession occurs in habitats with rich organic soil; secondary succession does not. Primary succession is always caused by human disturbances; secondary succession is not. Trees are often the first colonizing species in primary succession, but trees are never the first species in secondary succession.

Answers

Answer:

Primary succession can start from bare rock; secondary succession starts from organic soils.

Explanation:

Primary succession is when the growth of pioneer species rake place in an bare and new environment. The secondary succession is when the growth of species take place due to the disturbances in the primary succession. The secondary succession is based on fire, floods, or any man-made disturbances in the region.

What are sporophytes and gametophytes?

Answers

Answer:

A. Two different forms a plant can have

Explanation:

Higher plants, lower plants (mosses) and ferns undergo a life cycle called ALTERNATION OF GENERATIONS. In this life cycle, they switch between a haplontic and diplontic forms of life.

The haplontic (haploid) life form which produces haploid (n) gametes is called GAMETOPHYTE while the diplontic (diploid) life form which produces the spores that germinates is called SPOROPHYTE. Hence, sporophyte and gametophyte are two different forms a plant can have.

What conditions need to be present for an atom to form hydrogen bonds?

Answers

fluorine, oxygen, or nitrogen. These three elements are so electronegative that they withdraw the majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient.

For an atom to form hydrogen bonds, it needs to be bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and have a hydrogen atom attached to it.

Hydrogen bonds are intermolecular forces that occur between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom nearby. The highly electronegative atom, often nitrogen (N), oxygen (O), or fluorine (F), attracts the shared electrons in the covalent bond towards itself, creating a partial negative charge. This leaves the hydrogen atom with a partial positive charge.

The conditions necessary for hydrogen bonding to occur are:

Presence of a Hydrogen Atom: There must be a hydrogen atom (H) bonded to an electronegative atom (N, O, or F) in the molecule or adjacent molecules.Highly Electronegative Atom: The electronegative atom (N, O, or F) must have a strong attraction for electrons, creating a significant partial negative charge.Close Proximity: The electronegative atom with the partial negative charge must be close enough to another electronegative atom in another molecule or nearby region to allow for electrostatic attraction.

These conditions are essential for the formation of hydrogen bonds. The hydrogen bond itself is a relatively weak force compared to covalent or ionic bonds, but it is significant in biological systems and plays a crucial role in many biological processes. Hydrogen bonding contributes to the unique properties of water, the stability of protein structures, the binding of DNA strands, and various other molecular interactions.

In summary, for an atom to form hydrogen bonds, it must be bonded to a highly electronegative atom (N, O, or F) and have a hydrogen atom attached to it, with another electronegative atom in close proximity to allow for the formation of electrostatic interactions.

Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?

Answers

Answer:

The bird population might have to migrate in search for food or may decline in numbers.

Explanation:

This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.

Magnetic fields on the sun are produced by the sun’s uneven rotation and:
A. The movement of sunspots on the sun’s surface.
B. The movement of gases in the corona.
C. Gases in the convective zone.
D. Gases in the radiation zone.

Answers

Answer:

The correct answer is - C. Gases in the convective zone.

Explanation:

The heat of the sun causes the atoms to be ionized and create a charged gas known as plasma. These gases or plasma are move in the convective zone with the uneven and rapid rotation of the sun.

This creates the electric currents due to the charge in gases which ultimately create magnetic fields. Sun's rotation causes the sun's overall magnetic field to have some degree of order and to be somewhat stable over time.
