Explanation:
If an equation is dimensionally correct, it does not mean that the equation must be true. On the other hand, when the equation is dimensionally correct, the equation cannot be true. Dimensional analysis is a technique used to check whether a relationship is correct
Answer:
say a lighter car is going 80mph and a heavier car is going the same speed who do you think will have more damage i will say the heavier car
Explanation:
Answer:
Explanation:
Let the time period of A and B be Ta and Tb respectively. Similarly , amplitude of A and B be Aa and Ab respectively.
Given ,
Tb = 2 Ta
Ab = 2 Aa
maximum speed of a particle in SHM = ω A , where ω is angular velocity and A is amplitude .
ω = 2π / T
If maximum speed of A be Va
Va = ω A
= 2π( Aa / Ta )
If maximum speed of B be Vb
Vb = ω A
= 2π (Ab / Tb)
Va / Vb = (2π Aa / Ta) x (Tb / 2π Ab)
= (Aa / Ab) x (Tb / T a )
= .5 x 2 = 1
Va = Vb
Their maximum velocities will be equal.
The friend who has the greater displacement is the one who takes the longest path.
<h3>What is displacement?</h3>
The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.
Given, two friends leave a movie theater and take different buses to the same ice cream shop. One bus takes a longer route driving on a high-speed highway, while the other takes a shorter route on lower-speed local roads.
According to the definition. the displacement is neither larger not shorter but it is the shortest distance traveled by the person or particle.
Thus, friend who has longer path has larger displacement.
