Thank you sir

2×3×3×3=54, is this correct sir? I am confused since 51 is the key answer

Please help me solve this, Given digits 2,2,3,3,3,4,4,4,4, how many distinct 4 digit numbers greater than 3000 can be formed? Thank you

Please help me A certain steel tape is known to be 100000 feet long when the temperature of 70°F . When the tape is at a temperature of 10°F, what reading corresponds to a distance of 90000 ft? Coefficient of linear expansion of the tape is 5.833 x 10-6 per °F.

Sir, please help me how to get v(t)

Thanks a lot sir😊

Thank you Sir. Please help me solve again for the length of runway it will from the point of touchdown until it comes to a complete stop.

Sir thank you.

Thank you

The landing speed of an airplane is 360 kph. When it touches down, it puts on its brakes and reverses its engines. The retardation in its speed is 0.2 times the square root of its speed. Determine the time elapsed in seconds from the point of touchdown until the plane comes to a complete stop.

A car starting from rest picks up at a uniform rate and passes three electric post in succession. The post are spaced 360 m apart along a straight rod. The car takes 10 seconds to travel from the first post to the 2nd post and tales 6 seconds to go from the 2nd post to the 3rd post. Determine...

The depth of the crater of the Taal volcano was calculated in the following manner: From a helicopter flying vertically upward at 6m/s. A small bomb was released at the instant the helicopter was 20m above the crater surface. The sound of explosion was heard 9sec later. If the speed of sound is...

I forgot there is friction between the wall and the I forgot there is a friction between the wall and the ladder which is 0.20

I have this diagram, but I'm not sure about this 900 N, on top of the ladder already?

A 6 m ladder weighs 350N and is placed with its lower end on a horizontal floor and its upper end against the wall. The angle between the wall and the ladder is 30°. A man weighing 900N is to climb to the very top of the ladder. The coefficient of friction between the floor and the ladder to...
