Answer:
Momentum
Explanation:
Truck A has a greater momentum compared to Truck B.
Momentum is the product of mass and velocity of a body;
Momentum = mass x velocity
We see that the body with more mass and velocity will have a higher momentum.
Since the two bodies have the same mass, and the speed A is greater, then A will have a greater momentum.
The answer is A, transporting nutrients
Answer:
(a) 1.2 rad/s
(b) 1.8 rad
Explanation:
Applying,
(a) α = (ω-ω')/t................ Equation 1
Where α = angular acceleration, ω = final angular velocity, ω' = initial angular velocity, t = time.
From the question,
Given: α = 0.40 rad/s², t = 3 seconds, ω' = 0 rad/s (from rest)
Substitute these values into equation 1
0.40 = (ω-0)/3
ω = 0.4×3
ω = 1.2 rad/s
(b) Using,
∅ = ω't+αt²/2.................. Equation 2
Where ∅ = angle turned.
Substitutting the values above into equation 2
∅ = (0×3)+(0.4×3²)/2
∅ = 1.8 rad.
Im guessing this was supposed to be a multiple choice question. The answer is: "A radio receiver accidentally picked up its energy."
Answer:
λ = 4.9 m
Explanation:
given,
length of the organ pipe,L = 2.45 m
wavelength of the standing wave = ?
fundamental harmonic is given as,
λ = 4.9 m
Hence, the wavelength of the fundamental harmonic for standing waves in this shower is given by λ = 4.9 m
