The power required is 30 Watt.
Let us recall that power is defined as the rate of doing work. Hence, we can write as follows;
Power = Work done/ time taken
Now;
work done = Force × distance
Force = 30.0 N
Distance = 10.0 m
work done = 30.0 N × 10.0 m = 300 J
The power expended = 300 J/10.00 s = 30 Watt

Answer:
Bio psychology
Explanation:
Since, Dr. Wolski does research on the potential relationship between neurotransmitter deficiencies and mood states. His psychological specialty must be biological psychology.
Biological psychology, or bio psychology, is a discipline in which scientific investigation and clinical practice investigates the relation between brain and body. In this area scholars evaluate the biological basis of feelings, impulses and behaviors.
Answer:
d. causes the cell to make more viruses
Explanation:
Viruses depend on the host cells that they infect to reproduce. When found outside of host cells, viruses exist as a protein coat or capsid, sometimes enclosed within a membrane. The capsid encloses either DNA or RNA which codes for the virus elements.
An object in motion will remain in motion unless an outside force stops is.
Answer:
P = n P₀ 4.9 10¹⁴ Pa
Explanation:
The radiation pressure for full absorption is
P = S / c
Where S the pointing vector, which is equal to the intensity of the beam that is defined as the energy per unit area per unit time
The energy of the protons can be calculated
Em = K = ½ m v²
Area
A = π r²
Intensity is
I = n ½ m v² / π r²
I = ½ n m /π v² / r²
We replace
S = U / t A
S = ½ n m /π v² / r² Δt
The pressure is
P = 1/c (½ n m /π (v / r Δt)²2
Δt = 45 10⁻⁹ s
P = n [½ m /πc (v/r)²] 4.9 10¹⁴
The amount in square brackets is the pressure that a proton creates, which is why it is useful
P = n P₀ 4.9 10¹⁴ Pa
Where Po is the pressure created by a proton
