The free-body diagram of your question is; 2 downward forces (253 kg mass of barbell & 133 kg body mass of Kurlovich) acting together on a point supported by 2 upward forces as normal forces exerted by Kurlovich's feet.
Solving the normal forces exerted by 2 feet :
Summation of Forces Vertical = 0
2 Dowwnard Forces = 2 Upward Forces (2F)
253 + 133 = 2F
2F = 386 Kgs
F = 386 / 2
F = 193 Kgs (Normal Force Exerted by Each Foot)
To calculate the normal force exerted on each of Vladimir Kurlovich's feet while lifting the barbell, we need to consider the weights of Kurlovich and the barbell. The normal force is equal to the sum of the two weights.
To calculate the normal force exerted on each of Vladimir Kurlovich's feet while lifting the barbell, we need to consider the weight of Kurlovich and the weight of the barbell. The normal force is equal to the sum of Kurlovich's weight and the weight of the barbell, as it balances the gravitational force pulling them downwards. Kurlovich's weight can be calculated using his mass and the acceleration due to gravity, which is approximately 9.8 m/s².
Step 1:
Calculate Kurlovich's weight:
Mass = 133 kg
Acceleration due to gravity = 9.8 m/s²
Weight = Mass × Acceleration due to gravity
Weight = 133 kg × 9.8 m/s²
Step 2:
Calculate the weight of the barbell:
Mass = 253 kg
Acceleration due to gravity = 9.8 m/s²
Weight = Mass × Acceleration due to gravity
Weight = 253 kg × 9.8 m/s²
Step 3:
Calculate the normal force exerted on each foot:
Normal force = Kurlovich's weight + Barbell's weight

Answer:
that would be for force and motion and it would be newtons laws and that would be like inertia
Explanation:
it would be the law of inertia: every action has a equal ad opposite reaction.
hope this helps :)
Answer:
If these are your answer choices:
A. The sum of the horizontal forces is zero.
B. All the forces combine to give zero net force.
C. The forces occur as pairs of forces with equal magnitude and direction.
D. The forces all have the same magnitude.
The correct answer is B. All the forces combine to give zero net force.
A. Explanations that do not have experimental support
O
B. Conclusions that are supported by empirical evidence
O
c. Conclusions based on scientific consensus
O
D. Scientific claims supported by a collection of experiments
Pseudoscience is Explanations that do not have experimental support. therefore the correct answer is option A.
Scientific claims are statements made in science based on an experiment.
These Scientific claims are backed by the experimental data and their true results obtained from scientific investigation and experimentation.
Pseudoscience refers to false scientific assertions that defy accepted scientific theory. Ideas, processes, or activities that make such assertions are also referred to as pseudoscience.
Pseudoscience is often distinguished by contradictory, exaggerated, or unfalsifiable claims, reliance on confirmation bias rather than rigorous attempts at refutation, lack of openness to evaluation by other experts, absence of systematic practices when developing hypotheses, and persistence long after the pseudoscientific hypotheses have been experimentally disproven.
Although it frequently makes claims to be science, pseudoscience differs from science in that it does not follow accepted scientific practices like the scientific method, or the falsifiability of claims.
Thus, Pseudoscience is Explanations that do not have experimental support. therefore the correct answer is option A.

I think you are right on 1,2 and 4. I believe the answer would be D?!
