1) Time to get the highest point of it pathway>

Vf = Vo - g*t

Vf = 0 (condition of maximum height)
Vo = 5.33 m/s
g = 9.81 m/s

=> t = Vo / g = 5.33 m/s / 9.81 m/s = 0.543 s

2) Time to return from the highest point = time to get to the highest point = 0.543 s

Total time = 0.543s + 0.543 s = 1.086 s ≈ 1.09 s

Answer: 1.09 s

How do I calculate how many meters are in 7.2 light years?

Vikentia [17]

Answer:

68.2 Quadrillion meters

Explanation:

A lightyear is the distance that light travels in one year.

Speed of light is $3*10^8\ m/s$

So light covers 300,000,000 meters in one second.

One year has 31536000 seconds so , light covers

$9.461*10^{15}\ meters\ in\ one\ year$

so 7.2 light years is

$7.2*(9.461*10^{15})\\6.82*10^{16}$

so 7.2 light years is

6.82 x 10^(16) meters or

68.2 Quadrillion meters

A sample of oxygen gas with a volume of 3.0 m3 is at 100 C. The gas is heated so that

$\qquad\qquad\huge\underline{{\sf Answer}}$

According to Charles law, if pressure remains constant, volume varies directly with temperature. so we can infer that :

$\qquad\sf{\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}}$

So, we can use this formula to find out the final temperature of the gas ~

Note : Take temperature in Kelvin ( 100°C = 373 K )

$\qquad \sf \dashrightarrow \: \dfrac{3}{373} = \dfrac{6}{x}$

$\qquad \sf \dashrightarrow \: x = \dfrac{6}{3} \times 373$

$\qquad \sf \dashrightarrow \: x = 2 \times 373$

$\qquad \sf \dashrightarrow \: x =74 6 \: K$

Now, convert it to Celsius ~

i.e 746 - 273 = 473° C

So, the final temperature of the gas will be equal to 473° C
