I'm pretty sure the answer is B double check to make sure it isn't A
<h3>
Answer:</h3>
Acceleration of the cyclist: 2.67 m/s²
The acceleration of the cyclist is lower than that of the car.
<h3>
Explanation:</h3>
- Acceleration refers to the rate of change in velocity of a body in motion.
- It is calculated by; dividing the change in velocity by time.
- Acceleration = (Final velocity - Initial velocity) ÷ time
In this case;
For the cyclist;
Initial velocity = 0 m/s
Final velocity = 8 m/s
time = 3 seconds
Therefore;
Acceleration = (8 m/s - 0 m/s) ÷ 3 seconds
= 2.67 m/s²
For the car;
- Initial velocity = 0 m/s
- Final velocity = 30 m/s
- Time = 8 seconds
Therefore;
Acceleration = ( 30 m/s - 0 m/s) ÷ 8 seconds
= 3.75 m/s²
The acceleration of the cyclist is lower than that of the car.
A and D will increase the rate of solution of a salt in a water
Answer:
P-waves compression waves while S-waves are shear waves.
Explanation:
P- waves has the ability to travels through solid, liquid and gaseous medium while S-waves travels through only solid medium and restricted by liquid and gaseous medium. P-waves is a type of seismic wave that will reach first to the recording station as compared to S-waves because P-waves moves faster that S-waves that moves slower so that's why P-waves reach first on the recording station that is located 500 miles away.
Answer: C. Salt and Water
Explanation:
The reaction between an acid and a base will have salt and water as its end product. This process is known " Neutralization Reaction".
HCl + NaOH -----------> NaCl + H2O
Hydrochloric Sodium Sodium Water
Acid Hydroxide (base) Chloride(Salt)
