Answer:
"The weight of an empty bottle is 10N...Calculate the mass of the empty bottle."
w=Weight; m=Mass; g=Gravity
w=mg
w/g=m
10/9.81=m
1.019368kg = m
When water vaporizes into the air, it becomes humid out.
Answer: 1) It keeps us on the earth so that we can live on the earth and not flying someone else in the atmosphere and space. 2) It maintains the motion of motion of all the planets around the sun and moon around the earth. 3) It pulls all the object towards the earth. 4) The flowing of water in the rivers and seas.
Explanation:
Answer:
V_c=5.037 m/s
Explanation:
SOLUTION:
applying the conversation of energy, taking the datum at B
V_b=(m_c+m_b)gh_a=(3+0.5)*9.81*0=0 J
V_b=4.95 m/s
applying the conversation of linear momentum,
(m_c+m_b)V_b=m_c*V_c+m_b*V_b
V_b=6*V_c-34.66 (1)
utilising the relative velocity relation,
V_b/c=V_b-V_c
V_b=0.6-V_c (2)
from (1) (2)
6*V_c-34.66=0.6-V_c
7*V_c=35.26
the final velocity of the cart is
V_c=5.037 m/s
into (2)
V_b=0.6-V_c
V_b=0.6-5.037
= 4.437
Answer:
the Earth magnetic field in that region is about 89.09 T
Explanation:
If the magnetic field has an inclination of , and its horizontal component is 17 microTesla, then we can calculate the magnitude of the full magnetic field via the cosine function. Notice that the decomposition of a vector in horizontal and perpendicular components originates a right angle triangle where the vector is the hypotenuse of the triangle.
