Its mass and net force acting on it
Answer:
933. 3kg
Explanation:
We are given that
Mass,m=2000 kg
Initial speed,u=4.4 m/s
We have to find the maximum mass of grain if the speed of loaded freight car must not go below 3.0 m/s.
Final speed,v=3 m/s
By conservation of momentum
Initial momentum=Final momentum
Substitute the values
Mass of freight loaded car=2933.3 kg
Mass of grains=2933.3-2000=933.3 kg
Hence, the maximum mass of grains that it can accept=933.3 kg
Answer:
Polar covalent bond
Explanation:
When two atoms of unequal electro- negativity comes together to form bonds , there is unequal sharing of electrons between them , one of them acquaring partial positive and partial negative charge . Then they make bond due to mutual attraction.
Bond formation in HCl in gaseous state is an example .
Answer:
B) 3.33 m/s²
Explanation:
Given that,
The initial velocity of Juan, u = 10 m/s
Final velocity of Juan, v = 60 m/s
Time taken, t = 15 s
The acceleration is given by the relation
a = v-u/t m/s²
Substituting in the above equation
a = 60 - 10 / 15
a = 3.33 m/s²
Hence, the acceleration of the Juan is, a = 3.33 m/s²
When it travels to earth, it is likely to pass through and be absorbed by the gaseous water molecules and carbon dioxide because if it directly passes, it could cause harm to every existing living things on earth for its capacity is too harmful for a living thing to endure. That is why components such as CO2 and gaseous water molecules are in need.
