Answer:
C. L
Explanation:
Given that
Displacement of the object is given as
x = A sin(2 n f t)
We know that
Quantity Dimensions
Length/Amplitude L
Distance /Displacement L
Time T
Velocity LT⁻¹
Acceleration LT⁻²
Area L²
Mass M
Frequency T⁻¹
Given that x is the displacement that is why the dimensions of the displacement will be L.
Now by balancing the dimensions both sides ,the dimensions of the A will be L.
C. L
From the theory we know that:
c = λ / T
f = 1 / T
Where:
c = 3.
/ m (the speed of light)
λ is the wavelengh (in meters)
T is the period (in seconds)
f is the frequency (in Hz)
We were told that:
f = 7.30 . 
And we want to find out the value of λ.
c = λ / T
c = λ . 1/T
Swaping 1/T = f
c = λ . f
λ = c / f
λ = 3 . / 7.30 .
λ = 4.12 
m
Response: 4.12 m = 412 nm

Answer:
396.97°C
Explanation:
Charles' Law explains that at constant volume, the pressure of an ideal gas is directly proportional to its temperature (in Kelvin).
P₁ ∝ T₁
P₁ = kT₁
k = constant of proportionality
(P₁/T₁) = (P₂/T₂)
P₁ = 240.0 kPa
T₁ = Boiling point of water = 100°C = 373.15 K
P₂ = 431.0 kPa
T₂ = ?
(240/373.15) = (431/T₂)
T₂ = (431 × 373.15) ÷ 240
T₂ = 670.12 K
T₂ = 396.97°C
Hope this Helps!!!
The stiffness constant of the spring is 68,290.3 N/m
<h3>
Stiffness constant of the spring</h3>
Apply the principle of conservation of energy;
U = K.E
¹/₂kx² = ¹/₂mv²
kx² = mv²
k = mv²/x²
where;
- v is speed = 60 km/h = 16.67 m/s
- x is the distance
k = (1300 x 16.67²)/(2.3²)
k = 68,290.3 N/m
Thus, the stiffness constant of the spring is 68,290.3 N/m.

1. What is the skydiver's acceleration?
Initially, like any falling object, a skydiver's downward acceleration is 9.8 meters/seconds^2, or about 28-35 feet per second squared. This acceleration reduces over a few seconds and approaches zero as the skydiver reaches terminal velocity.
