Answer:
The magnitude of the magnetic force at 32.5⁰ to the field, is 2.22 F
Explanation:
Given;
magnitude of the magnetic force is F at 14.0⁰ with respect to the field.
To determine the magnitude of the magnetic force at 32.5⁰ to the field, we apply the following formula and solve with proportion;
f*Sin(14.0⁰) = F
f*Sin(32.5⁰) = ?
Therefore, the magnitude of the magnetic force at 32.5⁰ to the field, is 2.22 F
Answer:
This distance is measured from the center of the earth r = 3.4 10⁸ m
Explanation:
The equation for gravitational attraction force is
F = G m1 m2 / r²
Where g is the universal gravitation constant, m are the masses of the body and r is the distance between them, remember that this force is always attractive
Let's write the sum of force on the ship and place the condition that is balanced
F1 -F2 = 0
F1 = F2
Let's write this equation for our case
G m Me / r² = G m Mm / (r'.)²
The distance r is measured from the center of the earth and the distance r' is measured from the center of the moon,
r' = 3.85 10⁸ m
Let's simplify and calculate the distance
Me / r² = Mm / / (3.85 108- r)²
Me / Mm (3.85 108- r)² = r²
√ 81.4 (3.85 108 -r) = r
√ 81.4 3.85 108 = r (1 + √ 81.4)
34.74 108 = r (10.02)
r = 34.74 10⁸ / 10.2
r = 3.4 10⁸ m
This distance is measured from the center of the earth
1. The unknown is acceleration
2. The givens are the force(28,913N) and the mass(2350kg)
3. The equation is a=f/m where a is acceleration,f is force and m is mass
4.a=28913/2350 a=12.30340426
5. Therefore its acceleration is 12.30m/s²(rounded to nearest hundredth)
Answer:
the correct answer is C v = 60 cm / s
Explanation:
The speed of a wave is related to the frequency and the wavelength
v = λ f
They indicate that the object performs 20 oscillations every second, this is the frequency
f = 20 Hz
the wavelength is the distance until the wave repeats, the distance between two consecutive peaks corresponds to the wavelength
λ = 3 cm = 0.03 m
let's calculate
v = 20 0.03
v = 0.6 m / s
v = 60 cm / s
the correct answer is C
C. Combustion reaction.
These reaction are exothermic.
The reactions are:
2Mg + O2 -----> 2MgO
3Mg + N2 ------> Mg3N2
