A 105 kg astronaut carrying a 16 kg tool bag finds himself separated from his spaceship by 18 m and moving away from the spacesh

Ratling [72]

Answer:

$T=22.5sec$

Explanation:

From the question we are told that:

Mass of astronaut $m_a=105kg$

Mass of tool $m_t=16kg$

Distance $d=18m$

Velocity of separation $v_s= 0.1m/s$

Velocity of tool bag $v_t=4.5m/s$

Generally the equation for momentum is mathematically given by

$P=mv$

Therefore

Initial Momentum before drop

$P_1=0.1(105+16)$

$P_1=12.1$

Initial Momentum after drop

$P_2=-16(4.5)+105V$

Therefore

Since $P_1=P_2$

$-72+105V=12.1$

$V=0.8m/s$

Generally the equation for Time T is mathematically given by

$T=\frac{d}{V}$

$T=\frac{18}{0.8}$

$T=22.5sec$

Which can lead to an inaccurate tympanic temperature reading?

lozanna [386]

Significant ear drainage or a scarred tympanic membrane can lead to inaccurate results on a tympanic temperature reading.

<h3>Why inaccurate tympanic temperature reading?</h3>

Significant ear drainage or a scarred tympanic membrane can lead to inaccurate results on a tympanic temperature reading.

Although an ear infection or the presence of an ear infection will not significantly affect a tympanic thermometer reading.

If the client has been sleeping on one side, take the temperature on the other side as heat may be increased on the side against the pillow.

Recent consumption of a cold beverage will not affect tympanic temperature.

A mass of 3.0 kg rests on a smooth surface inclined 34° above the horizontal. It is kept from sliding down the plane by a spring

azamat

Answer:

The spring stretched by x = 13.7 cm

Explanation:

Given data

Mass = 3 kg

k = 120 $\frac{N}{m}$

Angle $\theta$ = 34°

From the free body diagram

Force acting on the box = mg sin $\theta$

⇒ F = 3 × 9.81 × $\sin34$

⇒ F = 16.45 N ------- (1)

Since box is attached with the spring so a spring force also acts on the box.

$F_{sp}$ = k x

$F_{sp}$ = 120 $x$ -------- (2)

The net force acting on the body is given by

$F_{net} = ma$

Since acceleration of the box is zero so

$F_{net} = 0$

$F - F_{sp} = 0$

$F = F_{sp}$

Put the values from equation (1) & (2) we get

16.45 = 120 $x$

x = 0.137 m

x = 13.7 cm

Therefore the spring stretched by x = 13.7 cm
