You can also enter units that are combinations of other units. Keep in mind that you have to indicate the multiplication of unit

The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). Of an object’s mass is m=10. kg, what is its weight
Given that The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). Of an object’s mass is m=10. kg,
The parameters to be considered are
Mass m = 10 kg
Acceleration due to gravity = 9.8m/s^2
Weight W = mg
substitute mass m and acceleration due to gravity g into the formula above.
Weight = 10 × 9.8
Weight = 98 N
Therefore, the weight of the body or object is 98 N
An opaque object is an object through which the light rays can not be passed and we can not see from that object while transparent object allows the passage of light. Hence red apple is unable to pass light, so it is a opaque object. Hence red apple looks red because it absorbs all color except red.
