First you get a tool and remove some of the warping from the tip.hehe. Then you neatly wrap the wires around the nail. Wrap more if you want to make it stronger. Make sure your able to fit the battery. connect the end of the wire to the positive side. Be careful.
Answer:
30 m/s
Explanation:
Speed is distance over time. 60 meters / 2 seconds, = 30 m/s.
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
Complete question is;
You are looking at a module specification
sheet that has the table of information
below. What is the maximum power of this
module in Watts to the nearest whole Watt?

160 in series
137.2 V
V_imp: 29.3 V
Ilsc: 8.60 A
I_Imp: 8.02 A
Dimensions (mm/in): 1000 x 1600 x 50 mm / 39.4" x 63" x 2"
Weight: 10 kg / 22 lbs
Answer:
P ≈ 235 Watts
Explanation:
Formula for power is;
P = IV
Now, for maximum power, we will make use of I_imp and V_imp given
Thus, P = I_imp × V_imp
We are given;
V_imp: 29.3 V
I_Imp: 8.02 A
Thus: P = 8.02 × 29.3 = 234.986 Watts
We are to approximate to the nearest whole watt.
Thus: P ≈ 235 Watts
Answer:
(c) 3 m/s;
Explanation:
Moment of inertia of the fish eels about its long body as axis
= 1/2 m R ² where m is mass of its body and R is radius of transverse cross section of body .
= 1/2 x m x (5 x 10⁻² )²
I = 12.5 m x 10⁻⁴ kg m²
angular velocity of the eel
ω = 2 π n where n is revolution per second
=2 π n
= 2 π x 14
= 28π
Rotational kinetic energy
= 1/2 I ω²
= .5 x 12.5 m x 10⁻⁴ x(28π)²
= 4.8312m J
To match this kinetic energy let eel requires to have linear velocity of V
1 / 2 m V² = 4.8312m
V = 3.10
or 3 m /s .
