I think the answer is Allele am not so sure of it and sorry if my answer is wrong or didn’t help okay
Answer:
hmm
Explanation:
By increasing the number of turns in the coil, strength of magnetic field, speed of rotation of the coil in the magnetic field and by decreasing the distance between the coil and the magnet the magnitude of the induced e.m.f. can be increased in generator/dynamo.
Answer:
323 m/s²
Explanation:
Given:
x₀ = 0 m
y₀ = 0 m
x = 29500 cos 65°
y = 29500 sin 65°
v₀x = 1810 cos 20°
v₀y = 1810 sin 20°
t = 9.20
Find:
ax, ay, θ
First, in the x direction:
x = x₀ + v₀ t + ½ at²
29500 cos 32° = 0 + (1810 cos 20°) (9.20) + ½ ax (9.20)²
25017 = 15648 + 42.32 ax
ax ≈ 221.4
And in the y direction:
y = y₀ + v₀ t + ½ at²
29500 sin 32° = 0 + (1810 sin 20°) (9.20) + ½ ay (9.20)²
15633 = 5695 + 42.32 ay
ay ≈ 234.8
Therefore, the magnitude of the acceleration is:
a² = ax² + ay²
a² = (221.4)² + (234.8)²
a ≈ 322.7
Rounded to 3 significant figures, the magnitude of the acceleration is approximately 323 m/s².
Explanation: Well, think about it if you see it on the logical end, there are 8 men that mean 16 legs. Then there are 4 legs of the couch as well that made it total of 20. If broken legs are of the men, then still the total will be 20 because the legs are still intact but 6 men left that means 12 legs are gone, if 3 legs break and 6 men leave. the number of legs remaining are 20–6*2–3=5.... so it's 5 I hope this helps! xoxo
1665183.6J
Explanation:
Given parameters:
Mass of Gold = 12400g
Initial temperature = 23°C
Final temperature = 1064°C
Unknown:
Energy required to melt = ?
Solution:
The amount of heat required to cause this temperature change to heat the gold bar is given as;
H = m c Ф
m is the mass of gold bar
c is the specific heat capacity of gold
Ф is the heat change
Specific heat capacity of gold = 0.129J/g°C
H = m c (Ф₂ - Ф₁)
H = 12400 x 0.129 x (1064 - 23) = 1665183.6J
