But from either world, at any given time, you can see varying portions of that lighted half – or various phases of the Earth or moon. The phases are always the reverse of …
Answer:
The weight of an automobile, W = 17640 N
Explanation:
Given that,
The mass of an automobile, m = 1800 Kg
The weight of an object is represented as the gravitational force acting on an object of mass 'm'. It given by the formula
W = m x g newton
Where,
g - acceleration due to gravity.
Substituting the given values in the above equation
W = 1800 Kg x 9.8 m/s²
= 17640 N
Hence, the weight of the automobile, W = 17640 N
Answer
given,
Q u = 8.7 m³/s
Q d= 0.9 m³/s
BOD concentration = 50 mg/L
a) BOD concentration at the down stream
= 4.69 mg/L
b) discharge = 9.6 m³/s
cross sectional area = 10 m²
velocity steam = 
= 0.96 m/s
time taken to move 50 km down stream =
= 52083.3 s
= 
= 0.6 days
now,
Answer:
Transformer
Explanation:
Transformers can increase (step up), or it can decrease (step down) voltage.
Answer
Acceleration
Acceleration Means rate of Change of velocity with respect to time.
acceleration due to gravity
when a body falls freely means no other force act on it except gravitational force that time velocity of object does not remains constant but it changes as it approaches towards the ground it means body get accelerated and this acceleration which is gained by the body due to gravitational force is called its acceleration due to gravity it is denoted by g. Acceleration due to gravity is different on different planet. SI unit of is m/s^2 . On earth its standard value is 9.80665m/s^2.
