1 ====> Your answers would be, Newton’s third law says that every time there is an ACTION force, there is also a REACTION force that is EQUAL in size and acts in the OPPOSITE direction.

2 =====> Newton’s third law states that forces must ALWAYS occur in PAIRS.

3 ===> Action forces ====> Tell the REACTION force.

A. Your bottom pushing on your desk seat: SEAT PUSHING UP ON YOUR BOTTOM.

B. A bat hitting a baseball: BASEBALL HITTING THE BAT.

C. Your finger pressing on your phone screen while texting: PHONE SCREEN PUSHING BACK ON YOUR FINGER.

Hope that helps!!!! : )

An ambulance with a siren emitting a whine at 1790 Hz overtakes and passes a cyclist pedaling a bike at 2.36 m/s. After being pa

Deffense [45]

Answer:

The speed of the ambulance is 4.30 m/s

Explanation:

Given:

Frequency of the ambulance, f = 1790 Hz

Frequency at the cyclist, f' = 1780 Hz

Speed of the cyclist, v₀ = 2.36 m/s

let the velocity of the ambulance be 'vₓ'

Now,

the Doppler effect is given as:

$f'=f\frac{v\pm v_o}{v\pm v_x}$

where, v is the speed of sound

since the ambulance is moving towards the cyclist. thus, the sign will be positive

thus,

$v_x=\frac{f}{f'}(v+v_o)-v$

on substituting the values, we get

$v_x=\frac{1790}{1780}(343+2.36)-343$

vₓ = 4.30 m/s

Hence, the speed of the ambulance is 4.30 m/s

A redecor travelling of 94 m/s s lows at a anstant

kotykmax [81]

Answer:

638 m.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 94 m/s

Final velocity (v) = 22 m/s

Time (t) = 11 s

Distance (s) =?

We can obtain the distance travelled by using the following formula:

s = (u + v) t /2

s = (94 + 22) × 11 /2

s = 116 × 11 /2

s = 1276 /2

s = 638 m

Thus, the distance travelled is 638 m.

A typical student listening attentively to a physics lecture has a heat output of 100 w . how much heat energy does a class of 1

nexus9112 [7]

Since each student emits 100 W, so 170 students will emit:

total heat = 100 W * 170 = 17,000 W

Convert minutes to seconds:

time = 50 min * (60 s / min) = 3000 s

The energy is therefore:

E = 17,000 W * 3000 s

E = 51 x 10^6 J = 51 MJ
