Answer: Liquid
“A substance will take on the shape of an open container if it is a Liquid. Explanation: The major state of matter are solid, liquid and gas. Liquid usually have a definite volume.”
Answer:
Explanation:
mass of charged particle m = 6 x 10⁻³ kg .
speed of particle v = 4 x 10³ m /s
speed of particle perpendicular to magnetic field = v sin37
= 4 x 10³ sin37
= 2.41 x 10³ m / s
Force on charged particle
= B q v , B is magnetic field , q is charge on particle and v is velocity perpendicular to B
Force = ma
= 6 x 10⁻³ x 8
= 48 x 10⁻³
Force = Bqv
48 x 10⁻³ = 5 x 10⁻³ q x 2.41 x 10³
q = 48 x 10⁻³ / (5 x 2.41)
= 3.98 x 10⁻³C.
Answer: The observation that all objects that have mass attract each other
In a fresh water lake
atmosphere
earths mantle
Answer:
63.57 kg
Explanation:
weight = 140 lbs
Let the mass is m.
1 lbs = 4.45 N
The weight of an object is defined as the force with which our earth attracts the body towards its centre.
Weight is the product of mass of the body and the acceleration due to gravity of that planet.
W = m x g
On earth surface g = 9.8 m/s^2
Now convert lbs in newton
So, 140 lbs = 140 x 4.45 = 623 N
So, m x 9.8 = 623
m = 63.57 kg
Thus, the mass is 63.57 kg.
