um well
Explanation:
get ur paddles and start rowing by putting ur hands on the paddles, and then rowing them by putting the paddle up, and then back into the water.
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
I Think The answer would be c I hope it helps My friend Message Me if I’m wrong and I’ll change My answer and fix it for you
a = F/(m1+m2)
1.2 = F/48,000
F = 57,600N
a = F/(m1+m3)
a = 57,600/24,000
a = 2.4 m/s^2
Answer:
11.6532 x 10⁻¹¹ J or 7.3 MeV is given off
Explanation:
Mass of an alpha particle = 4.0026u, ∴ mass of three = 12.0078u
Find the difference in mass.
Mass of three alpha - Mass of Carbon nucleus
12.0078u - 12u = 0.0078u
Since 1u = 1.66 x 10⁻²⁷ kg
Therefore, 0.0078u = 1.2948 x 10⁻²⁷
Now that we know Mass(m) = 1.2948 x 10⁻²⁷ and Speed (c) 3 x 10⁸ m²s⁻²
Formular for Energy ==> E₀ = mc²
E = (1.2948 x 10⁻²⁷) (3 x 10⁸ m²s⁻²)²
E = (1.2948 x 10⁻²⁷) (9 x 10¹⁶) J
E = 11.6532 x 10⁻¹¹ J
Or, if you need your energy in MeV
1 MeV = 1.60x10⁻¹³ J
Just do the conversion by dividing 11.6532 x 10⁻¹¹ J by 1.60x10⁻¹³ J
It will give you 7.3 MeV
