A thermometer has its term marked millimeter instead of degree celcuis .The lower fixed point is 30mm and upper fixed point is 1

Answer:

-125 degree celcuis

Explanation:

Using the formula;

θ - 0/100 - 0 = 45 - 30/18 - 30

Let us recall that the right hand side refers to the temperature in degrees centigrade while the right hand side stands for the temperatures in the scale of the thermometer. In both cases, the denominator is the fundamental interval.

So, we have;

θ/100 = 15/(-12)

-12θ = 1500

θ = 1500/(-12)

θ = -125 degree celcuis

A 1.20 kg water balloon will break if it experiences more than 530 N of force. Your 'friend' whips the water balloon toward you
soldi70 [24.7K]

Answer:

t = 0.029s

Explanation:

In order to calculate the interaction time at the moment of catching the ball, you take into account that the force exerted on an object is also given by the change, on time, of its linear momentum:

F=\frac{\Delta p}{\Delta t}=m\frac{\Delta v}{\Delta t}       (1)

m: mass of the water balloon = 1.20kg

Δv: change in the speed of the balloon = v2 - v1

v2: final speed = 0m/s (the balloon stops in my hands)

v1: initial speed = 13.0m/s

Δt: interaction time = ?

The water balloon brakes if the force is more than 530N. You solve the equation (1) for Δt and replace the values of the other parameters:

|F|=|530N|= |m\frac{v_2-v_1}{\Delta t}|\\\\|530N|=| (1.20kg)\frac{0m/s-13.0m/s}{\Delta t}|\\\\\Delta t=0.029s

The interaction time to avoid that the water balloon breaks is 0.029s
