Is gravity keeps the planets in orbit around the sun a. True b. False

1 answer:

True. It's a bit more complex than simply that, but for the question you asked the answer is A.
Inertia also works in tandem with gravity, and plants orbit they don't revolve (kudos on that! Small pet peeve of mine). Newtons laws of physics will help you understand this more; remember to keep in mind we are talking about space so the suns mass has gravitational pull, but space has no gravity- So inertia plays an important part as well.

what would the mass be of an object that was moving at a velocity of 35 m/s and has a kinetic energy of 500j be?

Answer:

0.816 kg

Explanation:

$E_k=\frac{1}{2}mv^{2}\\$

so $m=\frac{2E_k}{v^2}=\frac{2\times500}{35^2}=0.816 kg$

A box has a length of 18.1 cm and a width of 19.2cm tall ?

ladessa [460]

Volume = l*w*h = (18.1 cm)(19.2 cm)(20.3 cm) = 7,054 cm^3.

A surfer is moving at a constant velocity of 5.2 m/s north relative to a wave which is pushing him west at a constant velocity o

Vika [28.1K]

The speed and distances are directly proportional. Use ratios to solve for vertical y-distance. The ratio of x-distance west to y-distance north equals the x-velocity to y-velocity.

x/y = vx/vy
41/y = 8.6/5.2
41/y = 1.65
41/1.65 = y
24.8 m = y
