Answer:
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines.
Explanation:
There will be 4 forces on the phone in total.
1. gravity
2. normal force from the windshield
3. dynamic friction
4. a push from the car
The sum of all 4 forces must achieve an acceleration of 23,6 cm/s² or a total force of F = m * a = 0.1774kg * 0.236m/s² = 0.0419N.
Answer:
14 cm
Explanation:
F = (frac{uv}{u – v})
F = +ve
v = -ve
30 = (frac {25 {times} (-v)}{25 – (-v)})
v = (frac {25 {times} (-v)}{25+v})
v = 14cm
(Note that either negative or positive values go to show the positioning and hence, they are not a strong necessity in your final answer.)
So happy that i could help you!
Now this question could turn out to be easy for you!!
Answer:
1: Force, F = 200N
2: coefficient of friction = 0.5
Answer:
Explanation:
The relationship of between fundamental frequency, density of the string, length and tension of the string is:
where L/m is the linear density.
make F the subject of the formula
substitute the values
