<u><em>Answer:</em></u>498.82 cg is equivalent to 4988.2 mg
<u><em>Explanation:</em></u>cg stands form centigrams
mg stands for milligrams
From the standards of conversion, to convert from centi to milli, we multiply the amount ny 10
<u>This means that:</u>
1 centigram = 10 milligram
To convert 498.82 cg to mg, all we have to do is <u>cross multiplication</u> as follows:
1 cg ..................> 10 mg
498.82 cg .........> ?? mg
498.82 cg = </span>
<span> = 4988.2 mg
Hope this helps :)</span>
Answer:
69 (Nice)
Explanation:
The increase is three so when you add three to 66, well you get 69 :)
Hope this helps!

Answer:
9.4 x 10⁴ m/s
Explanation:
In circular or elliptical orbits , the angular momentum is conserved because torque is zero.
mr₁v₁ = mr₂v₂
2.2 x 10¹¹ x 1.8 x 10⁴ = 4.2 x 10¹⁰ v₂
v₂ = 9.42 x 10⁴ m/s.
= 9.4 x 10⁴ m/s
Answer:
В. An object with mechanical energy is always able to perform work.
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Furthermore, the mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body and it is measured in Joules.
Mathematically, it is given by the formula;
Mechanical energy = G.P.E + K.E
Hence, the true statement is that an object with mechanical energy is always able to perform work.
Answer:
Explanation:
The motion of the bullet is a uniformly accelerated motion, therefore we can find its acceleration by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the bullet in this problem:
u = 350 m/s is the initial velocity of the bullet
v = 0 is the final velocity (the bullet comes to a stop)
s = 0.125 m is the stopping distance of the bullet
Therefore, by solving the equation for a, we find its acceleration:
And the negative sign tells that the direction of the acceleration is opposite to that of the velocity.
