Answer:
The quantity of force is expressed by the product of mass (m) and acceleration (a). Mathematically the equation can be written as
F = ma
Where,
F= Force
m = mass
a = acceleration
When a force acts on an object the objects the objects have different effects of force. So let us know about the effects of force on an object.
Explanation:
Answer:
Explanation:
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object.
A species of insect will most likely go extinct as a result of which of the following changes to its environment?
A The introduction of a toxic pollutant to the entire range of the species
B The separation of the population into two geographic regions
C The gradual replacement of its primary food plant by a related species
D Climate change that extends the period of its reproductive activity
Answer:
A or D but I think MORE A
Explanation:
more like a than D
When a species becomes extinct all its genetic heritage is lost. Here The introduction of a toxic pollutant to the entire range of the species causes the extinction of the species and also the climate change. The correct options are A and D.
What is extinction?The process of evolution which leads to the disappearance of a population or species is defined as the extinction. The species evolve into new species in order ton adapt to the environmental changes in the genetic heritage.
The pollution from industries and vehicles will cause a drastic change in the level of oxygen in the atmosphere as well as water. This is responsible for the extinction of the most of the aquatic as well as terrestrial species.
Climate change is also an another factor which cause the destruction of the organisms. Many organisms are died due to global warming.
Thus the correct options are A and D.

How does the curved beak of a king penguin compare to the curved, cup-like structure of the pitcher plant?
They are both used to catch prey.
They are both used to collect water.
They both help avoid being eaten.
They both help protect the eggs.
please helpp
Both pitcher plant and king penguin use their physical adaptation to catch pray. The curved beak of the penguin helps them easily catch fish from snow similarly pitcher plant has the cup like structure to capture pray. Hence, option A is correct.
What is prey catching pitcher plant ?Pitfall traps, a prey-trapping mechanism with a deep hollow filled with digesting fluid, are modified leaves on a kind of carnivorous plants known as pitcher plants. Specialized leaves are used to create the traps in what are known as "genuine" pitcher plants. Using nectar, the plants draw in and suffocate their victim.
Flying, flying, or crawling insects that are out foraging are drawn to the hollow created by the cupped leaf by visual cues such nectar and anthocyanin colors.
Insects fall into the trap because the pitcher is slippery after being saturated by dew or nectar. To aid in preventing escape, the walls of the pitfall may be covered in waxy scales, protruding aldehyde crystals, cuticular folds, downward-pointing hairs, or lunate cells that originate from guard cells.
The sharp curved beak of penguin helps to easily catch their pray. Therefore, option A is correct.

How is an image formed by a plane mirror?
A) Light bounces off of the mirror and then appears to come from in front of the mirror.
B) Light passes through the mirror and then appears to come from behind the mirror.
C) Light passes through the mirror and then appears to come from in front of the mirror.
D) Light bounces off of the mirror and then appears to come from behind the mirror.
Answer:Light bounces off of the mirror and then appears to come from behind the mirror.
Explanation:Plane mirrors form images that are virtual, upright and the same size and shape as the object it is reflecting.
When rays of light from the object hits a plane mirror they bounces off the mirror,that is they undergo reflection, and appear to originate from behind the mirror, resulting to the formation of a virtual image.
The image formed appears to be behind the plane in which the mirror lies. A virtual image is an image that is formed at a location from which the rays of light appear to come from. The image can not be formed on a screen..

Describe how sound waves travel through a solid, liquid, and gas. Why does it move differently through these different mediums?
Answer:
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.

a 2 cm cube made of acrylic has a mass of 9.7 g. What is the density of the acrylic?
Answer:
here
volume of cube = l^3
=2cm^3
=8cm^3
now,
mass=(9.7÷1000)kg
=0.0097kg
volume=8cm^3÷100=0.08
we know that,
density=mass/volume
= (0.0097/0.08)kg/m^3
= 0.12125kg/m^3
Explanation:
the formula to calculate volume of cube is l^3 so here we find the volume of cube using this formula and then we convert gram into kilogram then convert cm into m then by applying the formula of density we find it density
A 2 cm cube made of acrylic has a mass of 9.7 g. The density of the acrylic is 0.12125 kg m3
What is density?Density is the mass of per unit volume.
[tex]Volume of cube = l^3\\=2cm^3\\=8cm^3[/tex]
mass 9.7 kg, converted into kilograms = 0.0097kg
[tex]Volume \;= \dfrac{8cm^3}{100} = 0.08[/tex]
Calculating the density
[tex]Density = \dfrac{mass}{volume} \\\\\dfrac{0.0097}{0.08} = 0.12125\;kg\;m^3[/tex]
Thus, the density of the acrylic is 0.12125 kg m^3.
