charle [14.2K]

Answer:

2.26 seconds

97m/s

Explanation:

1. Fall time

i) Find the vertical speed of the plane when the tanks were released

$V_{y,0}=84m/s\times sin(30\º)=42m/s$

That is the same initial vertical speed of the tanks.

ii) Find the fall time

$y-y_0=V_{y,0}\cdot t+g\cdot t^2/2$

$120=42t+4.9t^2$

$4.9t^2+42t-120=0$

$t=\dfrac{-42\pm\sqrt{(42)^2-4(4.9)(-120)}}{2\times 4.9}$

Only the positive value has aphysical meaning: t = 2.26 seconds.

2. Speed when they hit the ground

i) The horizontal speed is constant:

$V_x=84m/s\times cos(30\º)\approx72.5m/s$

ii) The vertical speed is:

$V_y=V_{y,0}+g\cdot t$

$V_y=42m/s+9.8m/s^2\cdot (2.26s)\approx64.1m/s$

iii) Total speed

$V=\sqrt{V_x^2+V_y^2}$

$V=\sqrt{(72.5m/s)^2+(64.1m/s)^2}\approx97m/s$

A hot-water radiator has a surface temperatue of 80 o C and a surface area of 2 m2 . Treating it as a blackbody, find the net ra

faust18 [17]

Answer:

925.04 J/s

Explanation:

T = 80 C = 80 + 273 = 353 K

To = 20 c = 20 + 273 = 293 K

A = 2 m^2

Use the formula for Stefan's law

Energy radiated per second

$E = \sigma A \left ( T^{4}-T_{0}^{4} \right )$

$E = 5.67 \times 10^{-8}\times 2\left ( 353^{4}-293^{4} \right )$

E = 925.04 J/s

Natalia lifts a bag of groceries 0.50 m by exerting a force of 36 N. How much work did she do on the bag?

Kruka [31]

<h3>Answer;</h3>

18 Joules

<h3>Explanation;</h3>

Work is the measures the transfer of energy when an object moves over a given distance.

Work is therefore given by; Force × distance

Force =36 Newtons

Distance = 0.5 meters

Hence; work = 36 N × 0.5 N

 = 18 Joules
