Answer:
a= -1.01m/s^2
Explanation:
A) We define all the variables that are given,
In this way
Acceleration = a
We obtain the Normal assuming 5% of the potato reading scale, so
We add forces to reach equilibrium, and you get
** The notation of the symbols is done according to the notation of the graph
So,
B) When making pressure it is understood that the shape takes the perpendicular direction of the direction of the force that is performed. If the pressure remains constant, the scale will also increase in its measurement.
Answer:
(a) 200.0628 N ; ( b) 4.08Kg
Explanation:
We know,
w = mg [here w= weight , m= mass , g= gravity]
now,
gravity on earth (g) =9.807 m/s²
mass of the spanner (m)=?
weight of the spanner on earth(w) = 40N
⇒ w = 40N
⇒m g =40N
⇒m = (40/g) Kg
⇒m= (40/9.807)Kg
∴m=4.08Kg
∴mass of the spanner on earth = 4.08Kg
We know,
Mass is the amount of matter in an object . So mass will remain same both on earth and jupiter.
So,
(b)The mass of the spanner on jupiter = 4.08Kg
Now,
The mass of the spanner on jupitar (m) = 4.08Kg
Gravity on jupiter (g*) = 5.g [5 times on earth]
= 5 . (9.807)m/s²
=49.035 m/s²
(a)
∴weight of the spanner on jupitar(w*) = m g*
=(4.08 x 49.035) N
=200.0628 N
The answer is A.
Hydroelectric, which is usually generating electricity through use of a dam.
Solar, energy from the Sun.
Biomass, organic material formed from plant matter.
