Answer:
15944.6 sec
Explanation:
d = distance of Pluto from earth = 32 AU = 32 x 1.496 x 10¹¹ m
v = speed of light = 1.08 x 10⁹ km/hr = ( 1.08 x 10⁹) (0.278) m/s
t = time taken for the communication to reach from probe to earth = ?
Using the equation
d = v t
Inserting the values given
32 x 1.496 x 10¹¹ = (( 1.08 x 10⁹) (0.278)) t
t = 15944.6 sec
t = 1.6 x 10⁴ sec
Answer:
c = 4,444.44
Explanation:
You have the following expression for the acceleration of the projectile:
(1)
s: distance to the ground of the projectile
To find the value of the constant c you use the following formula:
(2)
vo: initial velocity = 0 m/s
v: final speed = 200 m/s
Δs: distance traveled by the projectile = 3m - 1.5m = 1.5m
You replace the expression (1) into the expression (2):

You do the constant c in the last equation, then you replace the values of v, s and Δs:

The circumference of a circle is (pi) x (diameter)
The circumference of the cupcake is (pi) x (5 cm)
Halfway around is (1/2) x (pi) x (5 cm) = (2.5 pi cm) = <em>about 7.85 cm</em>
The 'why' appears up above, in the first 2 lines of this solution.
It is B because the other ones are good.
