The controversy over genetic differences in intelligence primarily relates to the misuse of genetic arguments for racial discrimination and the oversight of environmental influences on intelligence.
Explanation:The study of genetic differences in intelligence has been controversial due to several factors. The primary concern arises from the historical use of genetic arguments to justify racial discrimination. These views, although scientifically refuted, have at times resurged, as in the case of 'The Bell Curve'. Notably, the controversy arises from interpretations that link genetics and race with intelligence without accounting for the significant influence of environmental variables. Additionally, research has shown a closing of IQ gaps with increased access to education, pointing to nurture's critical role in intelligence development. The persistence of the idea that intelligence could be predetermined by race without adequate consideration of environment and socioeconomic factors contributes to the ongoing debate.
Moreover, there is a recognition that intelligence is affected both by genetics and environment, with environmental influences shaping the manifestation of cognitive abilities. Twin studies show a genetic component to intelligence, but conflict theorists note that IQ tests can be biased and do not always offer a fair assessment of a person's intellectual capabilities, reinforcing the complex interplay of genetics, environment, and social factors in the development of intelligence.
An 11.98-gram sample of zinc metal is placed in a hot water bath and warmed to 78.4°C. It is then removed and placed into a Styrofoam cup containing 50.0 mL of room temperature water (T=27.0°C; density = 1.00 g/mL). The water warms to a temperature of 28.1°C. Determine the specific heat capacity of the zinc.
Answer:
383.34 J/kg.K
Explanation:
From the question,
Heat lost by zinc = heat gained by water in the Styrofoam cup.
c'm'(t₁-t₃) = cm(t₃-t₂).............. Equation 1
Where c' = specific heat capacity of zinc, m' = mass of zinc, t₁ = initial temperature of zinc, t₂ = initial temperature of water in the Styrofoam cup, t₃ = temperature of the mixture
Make c' the subject of the equation
c' = cm(t₃-t₂)/m'(t₁-t₃).............. Equation 2
given: m' = 11.98 g = 0.01198 kg, m = density of water×volume of water = (1×50) = 50 g = 0.05 kg, t₁ = 78.4°C, t₂ = 27°C, t₃ = 28.1°C
Constant: c = 4200 J/kg.K
Substitute these values into equation 2
c' = 0.05×4200(28.1-27)/[0.01198×(78.4-28.1)]
c' = 231/0.602594
c' = 383.34 J/kg.K
If the mass of Mars is 0.11 ME (mass of Earth) and its radius is 0.53 RE (radius of
Earth), How much is the gravitational field g at the surface of Mars?
Given: ME=6.0x1024 kg and RE=6.4x106m
Answer:
3.8 m/s²
Explanation:
g = GM / R²
g = G (0.11 ME) / (0.53 RE)²
g = 0.39 G ME / RE²
g = 0.39 (9.8 m/s²)
g = 3.8 m/s²
Answer:

Explanation:
A ball is dropped from rest from a Cliff and falls for 3 seconds.
Neglecting air resistance, the final velocity of the ball is
m/s. (g = -9.8 m/s2)
Enter the answer
Answer:
-29.4 m/s
Explanation:
Given:
v₀ = 0 m/s
t = 3 s
a = -9.8 m/s²
Find: v
v = at + v₀
v = (-9.8 m/s²) (3 s) + (0 m/s)
v = -29.4 m/s
The final velocity of a ball dropped from rest for 3 seconds is -29.4 m/s.
How to find final velocity?Given the following information:
The ball is dropped from rest.
The acceleration due to gravity is g = -9.8 m/s².
The time the ball falls is t = 3 seconds.
Use the following formula to calculate the final velocity of the ball:
v = v_0 + g × t
where:
v is the final velocity of the ball
v_0 is the initial velocity of the ball (which is 0 in this case)
g is the acceleration due to gravity
t is the time
v = 0 + (-9.8 m/s²) × 3 seconds
v = -29.4 m/s
Therefore, the final velocity of the ball is -29.4 m/s.
The negative sign indicates that the velocity is downwards.

If one wave of 10 m amplitude meets constructively with another of amplitude 20
m, what is the new amplitude?
20 m
30 m
200 m
10 m
Answer:
B. 30m
Explanation:
This is because when a wave interferes constructively with another wave, they will add since constructive relates to joining or building up.
So, 10m + 20m equals a 30m wave.

If a race car is traveling South due to a 30N force and the parachute deploys resulting in a 10N force North what is the Net Force (or Resultant Force)?
a) 40n east
b) 40n south
c) 10n west
d) 20n south
Answer:
F = 20 N south
Explanation:
It is given that,
Force applied on the racing car in south direction is 30 N and parachute deploys resulting in a 10 N force due North.
We need to find the net force on the car.
Let North denotes +y axis and South denotes -y axis.
So, F₁ = +10 N
F₂ = -30 N
Net force is :
[tex]F=F_1+F_2\\\\F=10+(-30)\\\\F=-20\ N[/tex]
It means that the net force is 20 N and it is acting in south. Hence (d) is correct.
