Please help with the following physics questions

20 SKETCH THE VELOCITY- TIME GRAPH FOR A BODY MOVING WITH UNIFORM ACCELERATION UNIFORM VELOCITY 12 STATE HOW A VELOCITY- TIME GRAPH MAY BE USED TO FIND THE DISTANCE TRAVELED IN A GIVEN TIME THE ACCELERTION OF A BODY 12 A MARBLE IS THROWN VERTICALLY UPWARDS WITH AN INITIAL VELOCITY OF 10 MS . NEGLECTING AIR RESISTANCE FIND THE MAXIMUM HEIGHT REACHED BY THE MARBLE. THE TIME TAKEN FOR IT TO GET BACK TO ITS ORIGINAL ELEVATION 6 30 A GLASS BEARER HOLDS EXACTLY I LITRE ( IL ) AT OC. WHAT IS ITS VOLUME AT SOC . IF THE BEAKER IF FILLED WITH MERCURY AT OC , WHAT VOLUME OF MERCURY OVERFLOWS WHEN THE TEMPERATURE IS RAISED TO SOC? THE COEFFICIENT OF LINEAR EXPANSION ( A) OF GLASS = 6.9 x 10-6 OC-. THE COEFFICIENT OF VOLUME EXPANSION ( B ) OF MERCURY = 1. 82 X 10-4 OC-' 5 b DIF FOUR MOLES OF GAS AT A PRESSURE OF 5.4 ATM HAVE A VOLUME OF /20LITERS, WHAT IS THE TEMPERATURE ? IF THE PRESSURE REMAINS FIXED ? THE VOLUME IS INCREASED SO 240 LITERS, WHAT IS THE NEW TEMPERATURE? USE R = 8. 31 J mol K
