Answer:
+9.8m/s^2
Explanation:
The rate of gravity of the object is constant thriughout the surface of the earth.
For falling object, the rate of gravity is positive since the body is coming down (falling)
The rate of gravity is negative if the body is going up
The constant value for acceleration due to gravity is 9.8m.s^2
Since the object is falling, hence the acceleration due to gravity is positive.
Rate of gravity working on the object will be +9.8m/s^2

Speed is the distance travelled by an object whereas velocity is distance travelled by an object per unit time in a given direction.
Answer:
The answer is 2X as much illumination as connection in series
Explanation:
We are given from the question that the two bulbs are identical in power and resistance.
Firstly we know that In a series connection the Voltage across the circuit elements are different whereas In a parallel connection, the same value of voltage passes through all the circuit elements.
Power is expressed as ;
P = V^2/ R
An increase in voltage leads to an increase in power likewise if the voltage is reduced the power also reduces.
The two bulbs are said to be having the same resistances , so the voltage across them in a series connection will be halved
V =1/2V1 + 1/2 V2; making the illumination across them to be low.
Therefore in parallel the illumination will be twice as much the illumination when connected in series.
