Explanation:
the table and the wooden block
Simply draw the vector with the given coordinates.
Answer:
20 N
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma
= 5 × 4 = 20 N
Answer:
C.) 2H2O to 2H2+ O2 is the equation which represents a decomposition reaction.
Answer:
4 N
Explanation:
Electrostatic force is directly related to the charge of each object hence when the charge is doubled in only one of the objects, the force also double. If it's doubles on both objects, the force becomes four times. In this case, it's doubled on one object hence 2*2= 4 N
