use of pesticides increasing insect resistance
Answers
Answer:
use of pesticides increasing insect resistance
Explanation:
Pesticides are the chemicals used to kill or stop the growth of insects or pests in crops and plants.
Pesticides are used from a very long time and repeated use of same pesticide allowed insects to get use to of it and evolve themselves in a way that they become resistant to these pesticide, so pesticide do not have any effect on insects.
Hence, the correct answer is "use of pesticides increasing insect resistance".

In Florida, most of the rocks that are underground are a type of soft, white rock called limestone. If limestone is underwater for a long period of time, it begins to dissolve. Which of these processes most likely causes this change?
A. chemical weathering
B. erosion
C. deposition
D. physical weathering
Answers
In Florida, most of the rocks that are underground are a type of soft, white rock called limestone. Long-term submergence in water causes limestone to disintegrate. These processes most likely causes this change is called Physical weathering. Hence, Option D is the correct answer.
What is Physical weathering?Physical weathering is also known as mechanical weathering. It is the weakening of rocks followed by the disintegration due to the physical or mechanical forces including the actions on the rocks by the abrasion, frost chattering, temperature fluctuations and the salt crystal growth. Eventually, after many cooling and heating events, the rocks cracks and break into smaller pieces.
This same mechanical process applies when water freezes and thaws in the cracks of a rock. The chemical composition of the rock, however, remains the same in the process. In Florida, most of the rocks that are underground are a type of soft, white rock called limestone. Long-term submergence in water causes limestone to disintegrate.
These processes most likely causes this change is called Physical weathering. Hence, Option D is the correct answer.

A .5kg book sits on top of a student's desk which is 9m high. How
much gravitational potential energy does the book have as it sits on the desk?
Answers
Answer:
441J
Explanation:
Given parameters:
Mass of book = 5kg
Height = 9m
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy due to the position of the body.
It is given as:
Gravitational potential energy = mass x acceleration due to gravity x height
Gravitational potential energy = 5 x 9.8 x 9 = 441J
(i) 10 m (ii) 20 m (iii) 40 m (iv) 80 m
(c) The maximum potential energy of the object if its mass is 200g 1 mark

A power plant has two types of transformers. The first type of transformer triples voltage and the second type of transformer reduces voltage by half. If both transformers have the same number of primary turns, how many secondary turns does the first type of transformer have?
a. 3/2 of the secondary turns in the second type of transformer
b. 1/6 of the secondary turns in the second type of transformer
c. 2/3 of the secondary turns in the second type of transformer
d. 6 times the secondary turns in the second type of transformer
Answers
Answer:
d . 6 times the secondary turns in the second type of transformer
Explanation:
In transformer , voltage is increased or decreased according to ratio of no of turns in secondary to no of turns in primary coil . The relation is as follows
V₂ / V₁ = n₂/n₁
n₁ and n₂ are no of turns in primary and secondary coil and V₁ and V₂ are voltage in primary and secondary coil.
for first type , Let no of turn in primary = n and no of turn in secondary = n₁
V₂ / V₁ = 3
so
n₁/n = 3
n = n₁ /3
n₁ = 3n
For second type , let no of turn in secondary = n₂
V₂ / V₁ = .5
n₂/n = .5
n₂ = .5n
n₂ / n₁ = .5n / 3n
n₂ / n₁ = 1 / 6
n₁ = 6n₂
option d is correct .

While driving his sports car at 20.0 m/s through a residential neighborhood, Royston
comes up behind a slow-moving grandma and decides to pass her on the left. If
Royston can accelerate at 6.00 m/s2, how long will it take for him to reach a velocity of
30.0 m/s?
Answers
Answer:
1.67s
Explanation:
Given parameters:
Initial velocity = 20m/s
Acceleration = 6m/s²
Final velocity = 30m/s
Unknown:
Time taken = ?
Solution:
Acceleration is the rate of change of velocity with time. It is mathematically expressed as;
Acceleration = [tex]\frac{v - u }{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
6 =[tex]\frac{30 - 20}{t}[/tex]
6 = [tex]\frac{10}{t}[/tex]
10 = 6t
t = 1.67s

Answer:In a series circuit, the current is equal at every point around the circuit.
#CARRYONLEARNING #STUDYWELLAnswer:
The option that completes the sentence is;
Equal
Explanation:
A series circuit is a circuit arrangement whereby the components of the circuit are connected in a single chain by joining them end to end, thereby the current flows round the circuit through the singular path of the interconnected component in the circuit and therefore, the current which flows through each component as it flows round circuit, is equal at all points in the circuit.
Therefore, we have that in a series circuit, the current is equal at every point around the circuit.
how much energy must be absorbed by water with a mass of 0.5kg in order to raise the tempature from 30c to 65c
Answers
Answer:
62760J
Explanation:
Given parameters:
Mass = 0.5kg = 500g
Initial temperature = 30°C
Final temperature = 65°C
Unknown:
How much energy is absorbed by the water = ?
Solution:
To solve this problem, we use the expression below:
H = m C Δt
H = m x C x (t₂ - t₁ )
m is the mass
C is the specific heat = 4.184J/g°C
t₂ is the final temperature
t₁ is the initial temperature
So;
H = 500 x 4.184 x (65 - 30) = 62760J
