Answer: 735 N
Explanation:
Weight 
is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass 
of the body by the acceleration of gravity 
:
In the case of our planet Earth, the acceleration due gravity is 
. So for a man whose mass is 
, his weight is:
Answer:c
Explanation:
the rate of reaction increases as temperature increases
Answer:
Please check the attached file for the diagram
Explanation:
The velocity of the of the rowboat 
through the river is the resultant velocity. It is obtained taking a vector sum of the velocity in still water and the velocity of the river.
There are several ways to take this vector sum, but the question makes it simple for us to use Pythagoras's theorem because the East and North directions are perpendicular to each other.
Hence;
Wood, water, Forests. The rest can have harm to the nature.
Answer:4.32Nm
Explanation:
The magnitude of the torque will be the product of the force and its perpendicular distance from the force.
Force = 27N
Perpendicular distance = 16cm = 0.16m
Torque = 27×0.16
Torque = 4.32Nm
