Agata [3.3K]

Answer:

His fight or flight is being activated making the adrenaline go through him making him alert and ready for what's coming at him. Depending on what happens next Fight or Flight will take place. If the body feels in danger he will flee and if the body thinks it's not as big of a threat he can fight it off.

Satellite A A orbits a planet at a distance d d from the planet’s center with a centripetal acceleration a0 a 0 . A second ident

Kamila [148]

Answer:

$a_b=\frac{1}{4}a_0$

Explanation:

Since the centripetal force F_C is, in this case, the gravitational force F_G exerted by the planet, we can say that:

$F_G=F_C\\\\\frac{GMm}{r^{2} } =ma_c\\\\\frac{GM}{r^{2} }=a_c$

In the case of the satellite A we have:

$\frac{GM}{d^{2} } =a_0$

And in the case of the satellite B:

$\frac{GM}{(2d)^{2} } =a_b\\\\\frac{GM}{4d^{2} } =a_b\\\\\frac{GM}{d^{2} } =4a_b\\\\$

Finally, using these two expressions, we obtain :

$4a_b=a_0\\\\a_b=\frac{1}{4} a_0$

In words, the centripetal acceleration a_b is equal to one fourth of a_0.

rectangular plate, whose streamwise dimension (or chord c) is 0.2 m and whose width (or span b) is 1.8 m, is mounted in a wind t

Andrei [34K]

Answer:

See explaination for the details of the answer.

Explanation:

Density is a measurement that compares the amount of matter an object has to its volume. An object with much matter in a certain volume has high density An object with little matter in the same amount of volume has a low density. Density is found by dividing the mass of an object by its volume.

An object thrown vertically upward with a speed of 6 m/s from a height of h meters takes 10 seconds to reach the ground. set up

nexus9112 [7]

430m. We use the displacement formula x=v*t+1/2*a*t^2. Set upward to be the positive direction, so v=6m/s, a=-g=-9.8m/s^2 (gravity is pulling the object down), and t=10s. The displacement is -h(it's negative because the ending point is the ground, which is negative relative to the starting point). -h=60-4.9*100, h=430 m.
