Which of shakina's statements regarding acceleration and velocity is false? "when the acceleration and velocity are in opposite directions, the particle slows down." "when the acceleration and velocity are in the same direction, the particle speeds up." "when the acceleration is negative, the velocity can be either negative or positive." "when the acceleration is negative, the velocity must also be negative."

"When the acceleration is negative, the velocity must also be negative."

Explanation:

"When the acceleration and velocity are in opposite directions, the particle slows down."

TRUE

acceleration when opposite to velocity then the acceleration will become deceleration which will reduce the speed

"When the acceleration and velocity are in the same direction, the particle speeds up."

TRUE

When both are in same direction then it will help to increase the speed of the object.

"When the acceleration is negative, the velocity can be either negative or positive."

TRUE

Acceleration does not decide the direction of motion but it is rate of change in velocity

"When the acceleration is negative, the velocity must also be negative."

FALSE

Acceleration does not decide the direction of motion but it is rate of change in velocity

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
