Scientific inquiry may be defined as the process that follows the step of a question hypothesis, investigation, gathering evidence and communicating the results. it is commonly based on empirical or measurable evidence subject to specific principles of reasoning. it involves investing a given subject in a logical way to find evidence that supports the answer.
Answer: 109.89 Nm
Explanation:
The maximum torque will be calculated as the force multiplied by the perpendicular distance. This will be:
Torque = force × perpendicular distance
torque = 333 × 0.33
= 109.89 Nm
Answer:
a. 2040 m
b. 3000 m
c. 1697.5 m
Explanation:
Given that:
v(t) = 400 - 20t
0 ≤ t ≤ 10
We can get the formula for distance traveled by integrating the velocity, v(t), with respect to time:
=> s(t) = 400t - 10t²
a. First 6 mins:
t = 6 mins
s(t) = 400(6) - 10(6)²
s(t) = 2400 - 360
s(t) = 2040m
b. First 10 mins:
t = 10 mins
s(t) = 400(10) - 10(10)²
s(t) = 4000 - 1000
s(t) = 3000 m
c. When v(t) =290 m/mins
We insert this into the v(t) equation so we can find time t.
v(t) = 400 - 20t
290 = 400 - 20(t)
20t = 400 - 290
20t = 110
t = 110/20 = 5.5 mins
Now we insert that into the s(t) equation:
s(t) = 400(5.5) - 10(5.5)²
s(t) = 2200 - 302.5
s(t) = 1697.5 m
Answer:
39.375 A
Explanation:
To find the induced current, we use the relation
e = -ΔΦ/Δt, where
ΔΦ = change in magnetic flux of the bracelet
Δt = change in time, = 20 ms
Also, Φ = A.ΔB, such that
A = area of the bracelet, 0.005m²
ΔB = magnetic field strength of the bracelet = 1.35 - 4.5 = -3.15 T
ΔΦ = A.ΔB
ΔΦ = 0.005 * -3.15
ΔΦ = -.01575 wb
e = -ΔΦ/Δt
e = -0.01575 / 20*10^-3
e = 0.7875 V
From the question, the resistance of the bracelet is 0.02 ohm, so
From Ohms Law, I = V/R
I = 0.7875 / 0.02
I = 39.375 A
Liter
The Basic Unit for Volume
The liter, which is the basic unit of volume, was originally defined as the volume occupied by 1 kilogram of water, but today it's simply one-thousandth of a cubic meter
