Answer:
4 minutes 5 seconds
Step-by-step explanation:
Without additional information, we have to assume that one sequence can begin immediately after another, and that each takes the same amount of time. The total time for 7 sequences is 7 times the time for one sequence.
7 × 35 seconds = 245 seconds = 4 minutes 5 seconds
__
There are 60 seconds in a minute.
For 3. he answer is a
for 4 the answer is two
The force created by the object is 3.75 Newton.
Given
Mass of the object (m) = 1250 grams
Convert 1250 grams to kilograms by dividing it by 1000.
Mass (m) = 1.25 kg
Acceleration of the body (a) = 3 
From Newton's second law we know 
By Substituting in the above equation we get
Force = 1.25 x 3
Force = 3.75 
It can also be written as force = 3.75 N
Hence Force created by the body is 3.75 Newton.
