Answer:

x=4

Step-by-step explanation:

2x+4=12

Step 1: subtract both sides by 4

4-4=0 and 12-4=8

Now you are left with 2x=8

Step 2: divide 2 on both sides

2/2=1x and 8/2=4

Therefore, x=4

What force would have been applied to the bus from t=16 s to t=21 s? Assume the mass of the bus was 50 kg.

Svetllana [295]

Applying Newton's Second Law, it is found that the force, in Newtons, is given by:

$F = 10[v(21) - v(16)]$

Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:

$F = ma$

In this problem, mass of 50 kg, thus $m = 50$

Acceleration is <u>change in velocity divided by change in time</u>, that is:

$a = \frac{\Delta_v}{\Delta_t}$

In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:

$\Delta_t = 21 - 16 = 5$

$\Delta_v = v(21) - v(16)$

Thus, the force is given by:

$F = ma$

$F = m\frac{\Delta_v}{\Delta_t}$

$F = 50\frac{[v(21) - v(16)]}{5}$

$F = 10[v(21) - v(16)]$

Train A departs from Point A with a velocity of 150 km/h, Train B departs from Point B with a velocity of 100 km/h, and the dist

Mkey [24]

Let us consider the initial position of train A, $s_{0A}=0$ . This implies that $s_{0B}=500$ .

Moreover, we have

$v_A=150, \quad v_B=-100$

This implies that the two equations are

$s_A(t)=150t,\quad s_B(t)=500-100t$

The two trains meet if and only if their positions are the same, at the same time:

$s_A(t)=s_B(t) \iff 150t=500-100t \iff 250t=500 \iff t=2$

So, the two trains meet after 2 hours.

11.1÷0.01 is equal to

Lelu [443]

Answer:1110

Step-by-step explanation:Move over the decimal point to the right of .01 until it becomes a whole number (1). Then move over the decimal point of 11.1 the same amount of times you did for .01. This should get you 1110/1 which is 1110.
