Answer: E. and Electroweak in 1961 the only other, as
Explanation:
This is more an English grammar question than a physics question, so taking that perspective, one should look for the answer that best completes the sentence.
Based on the word "first" in the sentence, implying the need for a conjunction to join the two theories and the last part of the sentence does not give a reason but further supports the determination of the theory being the first unified theory.
So, to complete the sentence, the best option is;
Maxwell’s theory of Electromagnetism in 1865 was the first "unified field theory" and Electroweak in 1961 the only other, as no further theory has united the electroweak field with either the Strong (Hadronic) force or Gravity.
Answer:
Acceleration of Object A = 0.6 m/s²
Acceleration of Object B = 0.3 m/s²
Acceleration of Object A is double than the acceleration of Object B.
Explanation:
According to the Newton's 2nd law of motion, Acceleration of an object by a net force is directly proportional to the magnitude of that net force and in the direction of that net force and inversely proportional to the mass of the object
Mathematically
F ∝ a
F = ma
Given data:
F = 15 N
m₁ = 25 kg
m₂ = 50 kg
F = m₁a₁
a₁ = F/m₁
a₁ = 15/25
a₁ = 0.6 m/s²
F = m₂a₂
a₂ = F/m₂
a₂ = 15/50
a₂ = 0.3 m/s²
It can be seen that acceleration of Object A is double than the acceleration of Object B.
Answer:
The answer is a. Jumper
Explanation:
The change in the momentum is represented by the equation
Acceleration of any body is calculated by the product of the mass of the body and with the velocity the same mass is moving.
Since it is mentioned in the statement that m is the mass of the jumper then velocity will also be of the jumper to calculate the change in the momentum.
If the mass of bugle cord is taken, then its velocity will be taken for the equation.
Answer:
well the the answer to the hypossis is that i think the pencil will leave a mark on my finger.
observation the indent will be there for a little if i do not press hard harder i press the longer the mark stay what made this diffrence is that my hypossis got somthing wrong. the thumb will not leave a mark that you can barly see and the index finger has visble mark because the end of the pincel shaper
and pionty and the eares side is flay so i barly leaves a mark
