Answer:
103.57 Km/h
Explanation:
From the question given above, the following data were obtained:
Distance = 725 Km
Time = 7 hours
Speed =?
Speed can be defined as the distance travelled per unit time. Mathematically, it is expressed as:
Speed = Distance /time
With the above formula, we can calculate how fast he will drive (i.e the speed) in order to get there on time. This is illustrated below:
Distance = 725 Km
Time = 7 hours
Speed =?
Speed = Distance /time
Speed = 725 / 7
Speed = 103.57 Km/h
Thus, to get there on time, he will drive with a speed of 103.57 Km/h
Newton's Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” We calculate as follows:
F = ma
At the moon,
104 N = m(1.61 m/s^2)
m = 64.60 kg
Mass will still be the same when on earth since mass is conserved.
At earth,
F=ma
F = 64.60 kg (9.8 m/s^2)
F = 633.04 N <----ANSWER
The electrostatic force between two charged object is given by:
where
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is the separation between the two objects
We see that the force is inversely proportional to the square of the distance:
. Therefore, if the distance is doubled, the force decreases by a factor 4, and the new force will be:
and it will still be a repulsive force, since the two balloons have charges of same sign.
