The answer for sure is 5 m/s
The point of science is to disprove wrong theories, and continue our knowledge forward that way. it's a lot easier to disprove something than to prove something as a rule has to fail once to be wrong, while you would have to prove and show that the rule works on every possible scenario for it to be proven, which is impossible. as such, a scientist should question current theories for faults, and confirm ( not prove) or disprove them.
It's is True that your body temperature your body converts chemical potential energy into thermal energy
Answer:
The torque in the coil is 4.9 × 10⁻⁵ N.m
Explanation:
T = NIABsinθ
Where;
T is the torque on the coil
N is the number of loops = 9
I is the current = 7.8 A
A is the area of the circular coil = ?
B is the Earth's magnetic field = 5.5 × 10⁻⁵ T
θ is the angle of inclination = 90 - 56 = 34°
Area of the circular coil is calculated as follows;
T = 9 × 7.8 × 0.0227 × 5.5×10⁻⁵ × sin34°
T = 4.9 × 10⁻⁵ N.m
Therefore, the torque in the coil is 4.9 × 10⁻⁵ N.m
Answer:
When the y-coordinate is 12m, the x-coordinate of the particle is 24 m
Explanation:
Given;
y - component of acceleration = 1 m/s²
X - component of acceleration = 2 m/s²
distance traveled in y - direction, Dy = 12 m
To determine the distance traveled in X- direction, we obtain the duration of the displacement in y- direction.
Applying equation of motion;
Dy = ¹/₂ x at²
For distance traveled in x -direction;
Dx = ¹/₂ x at²
Dx = ¹/₂ x 2 x (4.9)² = 24.01 m ≅ 24m
Therefore, when the y-coordinate is 12m, the x-coordinate of the particle is 24 m
