The  final speed of the combined masses is 0.186m/s

According to the law of collision, the sum of the momentum of the bodies before the collision is equal to the momentum after the collision.

Mathematically;

m1u1 - m2u2 = (m1+m1)v

Substituting the given parameters;

0.24(0.6) - 0.26(0.2) = (0.24+0.26)v

0.144 - 0.052 = 0.5v

0.092 = 0.5v

v = 0.092/0.5

v = 0.184m/s

Hence the final speed of the combined masses is 0.186m/s

From summation and resultant of forces, the four answers are:

i.  ∅ = 34 degrees

ii. M = 0.48 kg

iii. V = 37.5 m/s

iv. V = 37.5i + 0j + 0k

Given that Three forces acting on an object are

F1 = (−2.00 i + 2.00 j) N

F2 = (5.00 i − 3.00 j) N

F3 = (−45.0 i) N.

If the object experiences an acceleration of magnitude 3.75 m/s2.

i. The direction of the force will be the direction of the acceleration.

Sum of the forces = (-2 + 5 - 4.5)i + (2 - 3 + 0)j

Sum of the forces = -1.5i -j

The acceleration direction will be

tan∅ = [tex]\frac{y}{x}[/tex]

tan∅ = [tex]\frac{1}{1.5}[/tex]

∅ = [tex]tan^{-1}[/tex] (0.67)

∅ = 34 degrees (approximately)

ii. The mass of the object can be calculated from Newton's law.

Resultant force = mass x acceleration.

Resultant force = [tex]\sqrt{1.5^{2} + 1^{2} }[/tex]

Resultant force = [tex]\sqrt{3.25}[/tex]

Resultant force = 1.8N

Then,

1.8 = 3.75M

M = 1.8 / 3.75

M = 0.48 kg

iii. If the object is initially at rest, the speed of the object after 10.0 will be calculated by using first equation of motion.

V = U + at

Where U = 0

V = 0 + 3.75 x 10

V = 37.5 m/s

Therefore, the speed of the object after 10.0 is 37.5 m/s

iv. The velocity components of the object after 10.0 are

V = 37.5i + 0j + 0k

We can ensure that the solar panels generate a current that Mark can use for his power station is by gradually increasing the brightness (amount) of light that we reflect on it.

Solar panel are photo-voltaic module or cells which means they uses sunlight as a source of energy to generate current.

when the sun rays hit a silicon crystal of the solar panel then the electron inside of the solar panel start to charge and travel rapidly. when such charged electron flow through the circuit then the solar panel generate electricity.

    So, to optimize the electricity generation, the energy of light is to be maximized which is determined by the frequency of the source.

The Earth's orbital period change is A: It would increase by 0.15 years

Using Kepler's third law which states that the square of the orbital period of the planet is directly proportional to the cube of its distance from the sun.

So, T² ∝ R³

T'²/T² = R'³/R³ where

So, making T' subject of the formula, we have

T' = [√(R'/R)³]T

T' = [√(1.1 AU/1 AU)³] × 1 year

T' = [√(1.1)³] × 1 year

T' = √1.331 × 1 year

T' = 1.15 × 1 year

T' = 1.15 years.

So, the change in the Earth's orbital period ΔT = T' - T

= 1.15 years - 1 year

= 0.15 years

Since this is positive, the orbital period increases by 0.15 years.

So, the Earth's orbital period change is A: It would increase by 0.15 years

From Newton's second law of motion, the average force on the ball by the racket is 98 Newtons. The correct answer is option C

Given that a 0.07 kg tennis ball, initially at rest, leaves a racket with a speed of 56 m/s. And the time for contact with the racket is 0.04 s, that is,

mass m = 0.07 kg

velocity v = 56 m/s

time t = 0.04 s

force f = ?

To calculate the average force on the ball by the racket, let us apply Newton's second law of motion.

Impulse = change in momentum

ft = mv

Substitute all the parameters into the equation above

0.04f = 0.07 x 56

make f the subject of the formula

f = 3.92 / 0.04

f = 98 N

Therefore, the average force on the ball by the racket is 98 Newtons. The correct answer is option C

Answer:

a.phytoplankton, zooplankton, small fish, large fish, large shark

Explanation:

The bottom level of the ocean's food chain is made up of one-celled organisms called phytoplankton. These tiny organisms are microscopic. They are so small they cannot be seen without a microscope. Billions of phytoplankton live in the upper part of the ocean. They take in the sun's light.

Phytoplankton, or plant plankton, is the first link in the food chain in the ocean. They require sunlight for photosynthesis, which they must perform. They therefore reside higher up in the shallow sunlight. Furthermore, they transform themselves into an ocean animal that can eat the “food” from the sun. Thus, option A is correct.

One-celled organisms known as phytoplankton make up the base of the ocean's food chain. These microscopic organisms are quite small. Without a microscope, they are invisible due to their small size. In the upper ocean, there are billions of phytoplanktons. They absorb the light from the sun.

Aquatic food webs are built on phytoplankton and algae. They are consumed by zooplankton, tiny fish, and crustaceans, which are the main consumers. Fish, tiny sharks, corals, and baleen whales all devour the primary consumers after them.

Therefore, phytoplankton, zooplankton, small fish, large fish, large shark  is a possible food chain in the ocean from start to finish.
