Explanation:
Given that,
Initial speed of the bus, u = 0
Acceleration of the bus, a = 0.5 m/s²
Let v is the velocity at the end of 2 minutes. The change in velocity divided by time equals acceleration.
So,
Let d is the distance cover during that time. So,
So, the final speed is 60 m/s and the distance covered during that time is 3600 m.
A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any point is specified by two values, the direction and the magnitude; such that it is a vector field. Mathematically it is described as,
Here
= Permeability at free space constant
= Current at each object
d = Distance to the center point of the two object
Two magnetic field due to the current in the same directions then is,
Replacing,
Therefore the correct answer is E.

Answer:
A!! The chemical weathering changes all of these, But The answer is its Composition
Explanation:
A
The buoyant force exerted on a 6,000-mL toy balloon by the air surrounding the balloon is 52.97N.
<h3>How to calculate buoyant force?</h3>
The buoyancy needed for an object can be calculated using the formula;
B = ρ × V × g
where;
- ρ and V are the object's density and volume respectively
- g is the acceleration due to gravity (9.81m/s²)
B = 6000 × 0.0009 × 9.81
B = 52.97N
Therefore, the buoyant force exerted on a 6,000-mL toy balloon by the air surrounding the balloon is 52.97N.
