A glacier is frozen and a geyser has boiling water coming from it. A glacier is usually still but it sometimes breaks and a geyser erupts. Also geysers are mostly rare and glaciers aren't.
Answer:
D
Explanation:
Moji could've chosen hardness tests that were not reliable.
The answer is to u question is: C
Answer:
f = 15 N
Explanation:
It is given that, when you push with a horizontal 15-N force on a book that slides at constant velocity, a frictional force also acts on it. Frictional force is an opposing force. The magnitude of applied force and frictional forces are same. So, the force of friction on the book is equal to 15 N.
Answer: F =3.218 * 10^-11 N
Explanation: The relationship between electric field intensity and force is given by
F = Eq.
F= Force on electron
E = strength of electric field = 2*10^5
q= magnitude of proton charge = 1.609 * 10^-19c
F = 2* 10^5 * 1 609 * 10^-16
F = 3.218 * 10^-11 N
