The answer to the question which method is not used to improve the tropical forest is letter "A" which is "increased logging". This method worsens the situation, cutting of increases results to the different type of catastrophes like floods, soil erosion, and others.
<u>Option a.</u>The particle of larger mass has more momentum.
How this is explained?
- Given two particles are of different mass & start from rest .
- They have same net force & distance travelled due to force is also constant.
- We know Kinetic energy
- and momentum p = mv .
- The same gives larger mass a smaller acceleration.
- The body which has larger mass will take a longer time interwal to move through same distance; the impulse given to larger mass is larger, thus larger mass will have a greater final momentum.
- Thus option(a).
What is a momentum?
- In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object.
- It is a vector quantity, possessing a magnitude and a direction.
- If m is an object's mass and v is its velocity (also a vector quantity), then the object's momentum p is :p=mv.
- In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.

Answer:
A=1.0.34 m
Explanation:
Given that
f= 1 s
x= 1 m
v = 1.72 m/s
We know that angular frequency ω is given as
ω = 2 π f
Now by putting the values in the above equation
ω = 2 π x 1
ω= 2 π rad/s
The velocity v is given as
A=Amplitude
A=1.0.34 m
Answer:
7.90 N/C
Explanation:
<u>Given:</u>
- = initial velocity of the electron =
- = final velocity of the electron = 0 m/s
- = distance traveled by the electron before coming to rest = 9 cm = 0.09 m
<u>Assume:</u>
- = charge on an electron =
- = mass of an electron =
- = electric field along the direction of motion
- = electric force on the electron
- = work done by the electric force
Since the electron is moving in the direction of the electric field, then the electric force on it will act in the direction opposite to its displacement whose magnitude is given by:
Since the displacement of the electron opposite to the direction of electron, the work done by electric force will be given by:
Since the electron enters the region of the uniform electric field with an initial speed u and travels a distance x to come to rest. The change in kinetic energy of the electron can be given by:
Since only the electric force is doing work on the electron, then the change in kinetic energy will be equal to the work done by electric force. This is due to the work-energy theorem.
Hence, the magnitude of electric field is given 7.90 N/C which point in the direction of the displacement of the electron.
Answer:
At the maximum height the ball will have an instantaneous velocity of zero. The formula for instantaneous velocity is
v = v₀ + at
Where v is the instantaneous velocity, v₀ is the initial velocity, a is the acceleration due to gravity, -9.8 m/sec², and t is the time.
We need instantaneous velocity to = 0.
0 = 20 - 9.8t : Isolate t => 1st step: Add 9.8t to both sides
9.8t = 20 : Isolate t => 2nd step: Divide both sides by 9.8
t = 2.04 seconds (approximately)
