Distance = velocity * time
1 hour and 15 minutes = 1.25 hours
25km/hr * 1.25 hours = 31.25km
Answer:
Mass = 873.6kg = 0.874 × 10^3 kg
Order = 3
Question:
Compute the order of magnitude of the mass of a bathtub half full of pennies.(Assume the pennies are made entirely of copper and the tub measures 1.3 m by 0.5 m by 0.3 m)
Explanation:
Given:
Dimensions of the tub = 1.3 m by 0.5 m by 0.3 m
Density of copper d = 8960kg/m^3
Mass = volume × density
Volume of tub = L×B×H = 1.3 × 0.5 × 0.3 = 0.195m^3
Since the tub is half full:
V = 0.195/2 = 0.0975m^3
Mass = 8960kg/m^3 × 0.0975m^3
Mass = 873.6kg = 0.874 × 10^3 kg
Order = 3
Note: Order of magnitude is of the form:
N = a × 10^b
Where;
b = order of magnitude
and
1/√10 </= a < √10
No, because the distance-time would show a constant velocity but the velocity-time graph shows an increasing velocity.
Answer: 24.97 kg
Explanation:
The gravitational force between two objects of masses M1, and M2 respectively, and separated by a distance R, is:
F = G*(M1*M2)/R^2
Where G is the gravitational constant:
G = 6.67*10^-11 m^3/(kg*s^2)
In this case, we know that
R = 0.002m
F = 0.0104 N
and that M1 = M2 = M
And we want to find the value of M, then we can replace those values in the equation to get
0.0104 N = (6.67*10^-11 m^3/(kg*s^2))*(M*M)/(0.002m)^2
(0.0104 N)*(0.002m)^2/(6.67*10^-11 m^3/(kg*s^2)) = M^2
623.69 kg^2 = M^2
√(623.69 kg^2) = M = 24.97 kg
This means that the mass of each object is 24.97 kg
