6 0

Explanation:

weight of water displaced=weight of sphere,

Since,  plastic sphere floats in water with 50.0% of its volume submerged

so, water=2 sphere,

so sphere's density = 1/2 of water's  density

Now,  weight of glycerin displaced=weight of sphere,

Also given This same sphere floats in glycerin with 40.0% of its volume submerged.

so glycerin =2.5 sphere,

so sphere's density = .4 of glycerin's = 1/2 of water's.

So glycerin = 1.25 water

A star ending its life with a mass of four to eight times the Sun's mass is expected to collapse and then undergo a supernova ev
Zielflug [23.3K]

Answer:

r = 16 Km

Explanation:

given  

m_n= 1.67 x 10^-27 Kg

M_star = 3.88 x 10^30 Kg  

A= M_star/m_n

A= 3.88*10^30/1.67 x 10^-27

A=2.28 *10^57  neutrons                           A = The number of neutrons  

we use the number of neutrons as a mass number because the star has only neutrons. = 1.2 x 10-15 m

r = r_o*A^1/3

r = 1.2*10^-15*2.28 *10^57^1/3

r = 16 Km

What is the acceleration of a race car if it has a mass of 1200kg and is moving with an engine force of 400N
meriva

Answer:

0.34 m/s^2

Explanation:

force=mass × acceleration

400 =1200 × acceleration

acceleration=400/1200

=0.34 m/s^2

A baseball player throws a ball borontally, which of the following statements best
MariettaO [177]

Answer:

Its vertical speed increases, and its horizontal speed remains the same.

Explanation:

Given that,

A baseball player throws a ball horizontally,

We know that,

A baseball player throws a ball horizontally, then vertical component of gravity will be increases but there is no acceleration in horizontal direction

So, horizontal velocity remains same.

Hence, Its vertical speed increases, and its horizontal speed remains the same.
