Answer:
<h3>The answer is 1.92 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 2.5 g
Volume = 1.3 cm³
We have
We have the final answer as
<h3>1.92 g/cm³</h3>

Answer:
4.454 N.
Explanation:
The force on a current carrying conductor in a magnetic field is given as,
F = BILsinФ................... Equation 1
Where F = magnetic Force, B = magnetic Field, I = current, L = Length of the wire, Ф = The angle between the conductor and the Field.
Given: B = 0.289 T, I = 6.91 A, L = 6.7 m, Ф = 19°
Substitute into equation 1
F = 0.289(6.91)(6.7)sin19
F = 0.289×6.91×6.7×0.33
F = 4.454 N.
Hence the magnetic force = 4.454 N.
Answer
1400 * 0.8 = 1,120
the useful energy output is 1,120 joules
Answer:
Its a parallel connection
Explanation:
The bulbs aren't in one line but two different parts, which makes it a parallel connection instead of a series connection.
Answer:
0.75km/min
Explanation:
I haven't learnt physics at all but I'll try
57336 - 57321 = 15km (Difference)
8.50 am - 8.30 am = 20 minutes (Difference)
If the car odometer adds up 15km every 20 minutes...
20 mins = 15km
1 min = 15 ÷ 20 = 0.75km
