If the textbook weight 19.6 newtons on venus, what is the strenght of gravity on that planet?

victus00 [196]

Answer:

8.91m/s²

Step-by-step explanation:

If you were referring to the question :

If a 2.2 kg textbook weighs 19.6 newtons on Venus, what is the strength of gravity on that planet then read on.

Weight is the force of gravity on an object and it can be computed using the formula:

W = mg

where:

W = weight (N)

m = mass (kg)

g = acceleration due to gravity

So we know the weight and the mass of the object, all we do is plug it into our formula and solve for what we do not know.

$W = mg\\\\19.6N = (2.2kg)(g)\\\\ \dfrac{16.6N}{2.2kg} = g\\\\8.91m/s^{2} = g$

Answer:

Step-by-step explanation:

$\theta=30^\circ=\frac{30}{180} \pi =\frac{\pi }{6}\\l=r \theta\\JK=2 \times \frac{\pi }{6} =\frac{\pi }{3} \approx 1.047circumference=2\pi r=2 \times \pi \times 2=4 \pi \approx 12.57 ~ft$

Jim leaves the gym running 5 mph. Ten minutes later Bob leaves the gym on his bike traveling at a speed of 8 mph. how long will

podryga [215]

Answer:

26 2/3 minutes: The two boys meet after 26 2/3 minutes

Step-by-step explanation:

Distance covered by Jim = Distance covered by Bob

(5 mph)(t) = (8 mph)(t - 10)

Simplify this by performing the indicated multiplication:

(5 mph)(t) = (8 mph)(t) - 80 mi

or:

80 mi = (3 mph)(t), or

80 mi

t = ----------- = 26 2/3 minutes

3 mph

What is the Slope of the line

vampirchik [111]

Answer:

$m=\frac{-3}{4}$

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Simply plug in 2 coordinates into the slope formula to find slope <em>m</em>:

$m=\frac{-4-(-1)}{5-1}$

$m=\frac{-4+1}{4}$

$m=\frac{-3}{4}$
