The answer to your question is B- They both described the inner part otherwise known as the inner core.

The inner core is hotter than the surface of the sun. The inner core is made out of iron and nickel. The inner core is extremely hot and is the last layer. It is a solid because of all the pressure from the other layers putting there weight onto this layer.

On level ground a shell is fired with an initial velocity of 49.0 m/s at 70.0 โ above the horizontal and feels no appreciable ai

xenn [34]

Answer:

Horizontal component = 16.8 m/s

Vertical component = 46.0 m/s

Explanation:

If we denote the initial velocity by v and the angle above the horizontal by θ,

the horizontal component of this initial velocity is given by

$v_x = v\cos \theta$

$v_x = (49.0\text{ m/s})\cos\,(70.0^\circ) = 16.8\text{ m/s}$

The vertical component is given by

$v_y = v\sin\theta$

$v_x = (49.0\text{ m/s})\sin\,(70.0^\circ) = 46.0\text{ m/s}$

What is the mass of an object if a force of 34 N produces an acceleration of 4 m/s/s?

antoniya [11.8K]

Use newton's second law, F = ma.
Force is 34 N and a is 4 m/s/s
34 = m(4), solve for m.
34/4 = 8.5 g
