who will give me class 9 difficult numerical for physics will be marked brain.... PL give me or seND pic of more than 50 numerical s of physics class the more you give the more you get brilliant and followers PL urgent. if you cannot give then don't give the answer other while it will be reported or give in my what sapp no. 8617260533 PL urgent |

Answer» Acceleration (a) =5m/s2=5m/s2 and Mass (m) = 1000 kg, therefore, Force (F) =? We know that, F=m×aF=m×a =1000kg×5m/s2=1000kg×5m/s2 =5000kg m/s2=5000kg m/s2 Therefore, required Force =5000m/s2=5000m/s2 or 5000 N Question 2: If the mass of a moving object is 50 kg, what force will be required to speed up the object at a RATE of 2ms–2? Solution: According to the question; Acceleration (a) =2ms−2=2ms-2 and Mass (m) = 50 kg, therefore, Force (F) =? We know that, F=m×aF=m×a =50kg×2m/s2=50kg×2m/s2 =100kg m/s2=100kg m/s2 Therefore, required Force =100m/s2=100m/s2 or 100 N Question 3: To accelerate a vehicle to 3m/s2what force will be needed if the mass of the vehicle is equal to 100 kg? Solution: According to the question: Acceleration (a) =3m/s2=3m/s2 and Mass (m) = 100 kg, therefore, Force (F) =? We know that, F=m×aF=m×a =100kg×3m/s2=100kg×3m/s2 =300kg m/s2=300kg m/s2 Therefore, required Force =300m/s2=300m/s2 or 300 N Explanation PLZ mark a BRAINLIST and like |
