These anisotropies in the temperature map correspond to areas of varying density fluctuations in the early universe. Eventually, gravity would draw the high-density fluctuations into even denser and more pronounced ones.

Neko [114]

Answer:

a) 120 N

b) 5 N

c) 0.2 N

d) Mass remains the same, and weight decreases.

Explanation:

<em>Use the formula W = mg, where mass is in kg, and gravitational field strength in N/kg.</em>

a)

W = mg

= 12 × 10

= <u>120 N</u>

b)

500 g = 0.5 kg

W = mg

= 0.5 × 10

= <u>5 N</u>

c)

20 g = 0.02 kg

W = mg

= 0.02 × 10

= <u>0.2 N</u>

d)

<u>Mass remains the same, and weight decreases.</u>

What is the gravitational energy of a 2.63kg
Elis [28]

Answer:

G.P.E = 368.3

Explanation:

Given the following data;

Mass = 2.63kg

Height, h = 14.29m

We know that acceleration due to gravity is equal to 9.8m/s²

To find the gravitational potential energy;

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

G.P.E = mgh

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

G.P.E = 2.63*9.8*14.29

G.P.E = 368.3

Note: the unit of gravitational potential energy is Joules.
