1) David's momentum is 12,000 kg m/s east

2) Serap's momentum is 15,000 kg m/s east

3) The total momentum is 27,000 kg m/s east

Explanation:

1)

The momentum of an object is given by

p=mv

where

m is the mass of the object

v is its velocity

In this problem, we have:

m = 600 kg is the mass of David+his dune buggy

v=20 m/s is their velocity (taking east as positive direction)

Therefore, David's momentum is:

p_d = (600)(20)=12,000 kg m/s

And the direction is the same as the velocity (east).

2)

Again, we can use the same equation:

p=mv

where this time

m is the mass of Serap+dunebuggy

v is their velocity

In this problem,

m = 500 kg is the mass of Serap + dunebuggy

v = 30 m/s is their velocity (positive since it is also in the east direction)

Substituting, we find

p_s = (500)(30)=15,000 kg m/s

And the direction is the same as the velocity (east).

3)

The total momentum of the entire system is given by

p = p_d + p_s

where

p_d is David's momentum

p_s is Serap's momentum

In this problem, we have the following data, found in the previous parts:

p_d = 12,000 kg m/s

p_s = 15,000 kg m/s

The two momentum have same direction (east), so we can simply add them together to find the total momentum:

p=12,000 + 15,000 = 27,000 kg m/s

And the direction is still East.

Using diagram differentiate between solenoid and a toroid
damaskus [11]

The Toroid is form when you have wound conductor around circular body. In this case you have magnatic field inside the core but you dont have any poles because circular body dont have ends. This can be used where you want minimum flux leakage and dont need magnatic poles. i.e. toroidal inductor, toroidal transformer.


The Solenoid is forn when you wound conductor around body with limb. In this case magnatic field creates two poles N and S. Solenoids have little bit flux leakage. This used where you want magnatic poles and flux leakage is not an issue. i.e. relay, motors, electromagnates.

1 == toroid


2= solenoid

A ball is dropped from the top of a building.After 2 seconds, it’s velocity is measured to be 19.6 m/s. Calculate the accelerati
zlopas [31]

Answer:

acceleration, a = 9.8 m/s²

Explanation:

'A ball is dropped from the top of a building' indicates that the initial velocity of the ball is zero.

u = 0 m/s

After 2 seconds, velocity of the ball is 19.6 m/s.

t = 2s, v = 19.6 m/s

Using

v = u + at

19.6 = 0 + 2a

a = 9.8 m/s²
