I'm not sure you guys are prepping for UTME with the kind of questions you're throwing in especially the mathematics. If you feel like flexing muscles with strong questions, you can move over to the nairaland maths clinic. Most of these questions you guys are posting are beyond the scope of UTME.
Thank God, u observed it too.

1. A car travelling at 50m/s from rest covers a distance of 10km in 40min. Calculate the acceleration.
Education / Re: Jamb Lecture/past Questions For Science/art Students by Destilo(f): 7:44am On Oct 06, 2014
mathefaro:
First and foremost, convert the average velocity to m/s by multiplying by 5/18
==> v = 54 * 5/18 = 15m/s;
Then recall that distance = average velocity * time taken i.e. S = vt
S = ?; v = 15m/s; t = 10s
Therefore, S = 15 * 10 = 150m


Since the car started from rest, initial velocity, u = 0, v = 30m/s; t = 6a; a = v/t = 30/6 = 5m/s2; S = ?
So with the available parameters, S, u, a and t, the appropriate equation to use is S = ut + (1/2)*at2;
Therefore, S = 0(6) + 0.5*5*36
S = 0+ 90
S = 90m


V - U = 5m/s; t = 30s; U = 20m/s;
a = (V - U)/t = 5/30 = 1/6m/s2
S =ut + ½at2
S = 20(30) + ½*1/6*30*30
==> S =600 + 75
==> S = 675m

u = 50m/s; v = 0; t = ?, g = 10m/s2
=> V = u - gt (minus because the body is going up against gravity)
=> 0 = 50 - 10t
=> 10t = 50
=> t = 5s

Good morning lovely people

Wao...u re gud

Help me in dis, I need to know if I got it right.thank u.

1. The average velocity of a car is 54km/h. what is the distance covered if the time taken is 10s?

2. A car starts from rest and travels at uniform acceleration until it attains a velocity of 30m/s after 6s. The distance covered is?

3. A man increased his speed by 5m/s after 30s, if his initial velocity was 20m/s. The average distance covered if his speed was at uniform acceleration would be?

4. A ball is thrown vertically upwards from the ground with an initial velocity of 50m/s. What is the total time spent by the ball in the air (g=100m/s.sq)

To convert the binary number(110011.1001) to hex is easy just break it into groups of four numbers, 0011 0011 . 1001 (note that I added extra two 0s to the left to make it balanced) now with it broken into segments of four use the conversion for binary, so using the table below you get your Hex number 33.9

Hex Binary
0 = 0000
1 = 0001
2 = 0010
3 = 0011
4 = 0100
5 = 0101
6 = 0110
7 = 0111
8 = 1000
9 = 1001
A = 1010
B = 1011
C = 1100
D = 1101
E = 1110
F = 1111

Now for octal,all you do is break it down into groups of three, your number(110011.1001) broken down would look like this 110 011 . 100 100 (note that I added extra two 0s to the right side to make it balance) then all you do is convert to octal using the table below. which you get 63.44 in octal.

Octal Binary
0 000
1 001
2 010
3 011
4 100
5 101
6 110
7 111

hope that helps.

Moving coil Galvanometer is an instrument that is used for the DETECTION of electric currents through electric circuit..

and

Hot Iron Ammeter is an instrument used to MEASURE the flow of electric current in a circuit.

But u can still used maths

d answer is. =210°
Solution;
Bearing of b from a = 30° (falling on d 3red cordrant )
Therefore 90-30=60° (angles in a right angled triangle )
Hence 90-60=30°
Then 30+180=210°

Its physics question not maths...
ok...its still complicated...
what about the 5km?
