Since there are no aurora observed on Venus we can conclude that Venus a. lacks atmospheric oxygen b. is too hot for magnetic fo
Brrunno [24]

Answer:

Yes, Venus does not have the same magnetic field as that of earth's  

Explanation:

Instead, there are solar wind particles that can deeply penetrate the venus atmosphere and can collide with the other carbon atoms already present in the air but lacks oxygen and thus does not have that strong magnetic field which would deflect the suns rays and create aurora in the sky at night.

When a projectile reaches the highest point the vertical component of the acceleration is:
Mazyrski [523]

Answer:

The acceleration is g.

Taking the upward direction as positive

V = Vy y - 1/2 g t^2

Taking the downward direction as positive

V = -V y + 1/2 g t^2

One can choose either direction as positive, but the acceleration is

the same as g (it is g) while the projectile is in the air.

A force is applied to a block to move it up a 30° incline. The incline is frictionless, the block is initially at rest, F= 65.0
muminat

Answer:

0.96 m, upward

Explanation:

\theta=30^{\circ}

F=65 N

M=5 kg

Initial velocity, u=0

t=0.550 s

Fcos\theta-Mgsin\theta=Ma

Where g=9.8 m/s^2

Substitute the values

65cos30-5\times 9.8sin30=5a

31.8=5a

a=\frac{31.8}{5}=6.36 m/s^2

S=ut+\frac{1}{2}at^2

S=0+\frac{1}{2}(6.36)(0.55)^2=0.96 m

Hence,the block moves upward because displacement is positive.
