It is customary to work in SI units. Calculate the volume of the concrete. V = 3.7*2.1*5.8 cm³ = 45.066 cm³ = 45.066 x 10 ⁻⁶ m³ The mass is 43.8 g = 43.8 x 10⁻³ kg The density is mass/volume. Density = (43.8 x 10⁻³ kg)/(45.066 x 10⁻⁶ m³) = 971.9 kg/m³ Answer: 971.9 kg/m³
Answer:
103.1 V
Explanation:
We are given that
Initial circumference=C=168 cm
Magnetic field,B=0.9 T
We have to find the magnitude of the emf induced in the loop after exactly time 8 s has passed since the circumference of the loop started to decrease.
Magnetic flux=
Circumference,C=
cm
When t=0
E=
t=8 s
B=0.9
Acceleration (magnitude anyway) = (change in speed) / (time for the change) . Change in speed = (10 - 30) = -20 m/s Time for the change = 4.0sec Magnitude of acceleration = -20/4 = <em>-5 m/s² </em>
