for a given type of wave in a given medium a larger frequency means a smaller wavelength
Answer: 
Explanation:

where;
= final velocity = 0
= initial velocity = 60 km/h = 16.67 m/s
= acceleration
= distance
First all of, because acceleration is given in m/s and not km/h, you need to convert 60km/h to m/s. Our conversion factors here are 1km = 1000m and 1h = 3600s

Solve for a;

Begin by subtracting 

Divide by 2d

Now plug in your values:



If you're wondering why I calculated acceleration first is because in order to find force, we need 2 things: mass and acceleration.

m = mass = 900kg
a = acceleration = -2.78m/s

It's negative because the force has to be applied in the opposite direction that the car is moving.
Thermal energy always flows spontaneously from the body that is at a higher temperature to the body that has a lower temperature.
In this case, the thermal energy flows from the hot beverage that is at the temperature t1 to the ice cube at the temperature t2 until the two reach the same temperature t3.
Where:
t1> t2 <t3.
The ice cube would emit heat if the temperature of the liquid with which it comes in contact with the smaller than that of the ice.
