Explanation:
Recall that scientific notation involves expressing the number in powers of ten, and using a multiplicative factor whose value is larger than or equal to 1 (one) and strictly smaller than 10 in the form:
and with n an integer value.
in our case, notice that 0.00016 = 16 / 100000 = 1.6 / 10000
and that denominator can be expressed as: 10^4, and can also be brought to the numerator as a negative power of ten:
1.6 / 10000 = 1.6 / 10^4 = 1.6 * 10^(-4)
Answer:
θ =28.07⁰
Explanation:
when van moves around an unbanked curve, horizontal component of normal force is equal to centripetal force
---(1)
There is no motion in vertical direction, so vertical component of normal force is balanced with weight of block i.e.
----(2)
divide (1) and (2)
v = 28 m/s
r = 150 m
g = 9.8m/
θ = 28.07⁰
