Explanation:
Since the hydrangeas are changing color depending on whether the soil is acidic or basic, they must have an indicator.

If the charged particle moves in the magnetic field or electric field, then it experiences magnetic force or electric force because of its magnetic or electric properties.
<h3>What is magnetic field?</h3>
The magnetic field is the region of space where a charged object experiences magnetic force when it is moving.
When a charged particle such as an electron or proton moves inside a conductor, magnetic lines of force rotate around the particle. This relative motion causes the magnetic field to generate.
Thus, If the charged particle moves in the magnetic field or electric field, then it experiences magnetic force or electric force because of its magnetic or electric properties.

Answer:
The blender was running for 35 seconds.
Explanation:
Given:
Power of the blender is, 
Work done by the blender is, 
We know that, power is defined as the rate at which work is done by the body.
Here, we are given the power and work done and we are asked to find time taken.
Let the time of running of the blender be 't' seconds.
So, the power of the blender is given as:

Rewriting the above in terms of 't', we have

Plug in the given values and solve for 't'. This gives,

Therefore, the blender was running for 35 seconds.
