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 . Somass 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
how far away is all 9 planets from the sun
The magnitude of her velocity with respect to the shore will be 5.70 Km/h. The change of displacement with respect to time is defined as velocity.
Velocity is defined as the change in displacement with respect to time. The quantity of velocity is a vector quantity. It is a component that is time-based. It is measured in meters per second.
The given data in the problem is;
Q is the magnitude of Velocity of the boat = 4.5 km/hr
P is the magnitude of Velocity of the river flowing = 3.5 km/hr
R is the resultant of velocity P and Q=?
θ is the angle between the two velocities = 90°
From the law of vector addition;
Hence the magnitude of her velocity with respect to the shore will be 5.70 Km/h.
To learn more about the velocity refer to the link;
Answer: The magnitude of her velocity ( v ) with respect to the shore is 5.70 km/h.
Explanation:
Magnitude of Velocity of the boat = Q
Magnitude of Velocity of the river flowing = P
R = Resultant velocity due to velocity of boat and velocity of river.
Applying Law of triangles of vector addition :
From the figure attached:
P = 3.5 k/h, Q = 4.5 km/h
The magnitude of her velocity ( v ) with respect to the shore is 5.70 km/h.
Surface tension - My definition -
It's exactly what it says - The tension of a surface with a liquid (such as water), caused by the attraction of the surfaces layer ---- I hope this helps ---- I actually did research it and got some of this from a dictionary, but I changed some of it, too.... Sorry if this doesn't help :)

Answer:
so your wondering how electricity goes from power plants to your home? well, here's why.The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines. It travels through distribution lines to your neighborhood.
The theory of evolution is that organisms evolve over time.
