this chemical equation represents a <em>chemical</em> reaction
Answer:
98.4 N
Explanation:
Given that the body weighs 800 N on earth.
Thus,
Weight = mass x acceleration due gravity
i.e W = mg
800 = m x 10
m =
= 80 kg
The mass of the body is 80 kg.
To be able to determine its weight on the planet, we have to first calculate the gravitational pull of the planet.
But,
g =
Where: G is the Newton's universal gravitation, M is the mass of the planet and r is the radius of the planet.
g =
=
= 1.2275
g = 1.23 m/
Thus,
Weight of the body on the planet = mg
= 80 x 1.23
= 98.4 N
The weight of the body on the planet is 98.4 N
Answer:
-18 Nm
Explanation:
Impulse = Change of Momentum
I = ∆p
I = mv2 - mv1
I = 3 x 3 - 3 x 9
I = 9 - 27
I = -18 Nm
In transistor,
Emitter current is equal to the sum of base current and collector current.
