D. 289
Take the formula:
K=5/9(Fahrenheit-32)+273
Plug in Fahrenheit
K=5/9 (60-32)+273
From here it is simple math and you can plug it into your calculator getting 288.5555556 and round to 289
Answer:
Earth because of greater gravity
Answer:
1. high, low
2. decreasing, increasing
3. low, high
4. kinetic, thermal
Explanation:
When the boy is skating, he has kinetic energy. As he slows, the kinetic energy is being converted to thermal energy. When he stops, all the kinetic energy has been converted to thermal energy. At all times, the total energy is the sum of kinetic and thermal energies.
Answer:
Explanation:
Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:
which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:
and
so
a = 3.0 m/s/s
