Answer:
negative force
Explanation:
Here woman is applying the force to stop the child or to prevent him from running.
Here we know that the force applied by the woman is opposite to the motion of child but here the child is not displaced by this applied force but the child is only prevented his running.
So here the work done by the woman is zero as there is no displacement by this force.
But here we can say that the the force of woman is against the motion of child so here this force is opposite force and hence it is termed as negative force here.
so correct answer will be
negative force
Answer:
108 extended days
Explanation:
Regular school hours a day = 6 hr
No. of school days to make up by extending the regular hours = 3 days
Amount of time added to the regular hours of school = 10 min
No. of extended school days to make up the 3 school days by following the above mentioned criteria be x.
Time of school hours in 3 days = 
are required to make up 3 days of school having 6 hours of regular timing with 10 minutes of add-on time each day.
The factor that can have a significant influence on a planet’s surface temperature is its atmosphere.
<h3>What is the role of the atmosphere in the planet's temperature?</h3>
The atmosphere plays a fundamental role in the Earth planet's temperature because it allows the entry and out of certain types of radiation that may increase the temperature.
The role of the atmosphere in the Earth's temperature is well documented because our temperature is thick and it increases its homeostatic temperature balance.
In conclusion, the factor that alters a planet’s surface temperature is its atmosphere.

Answer:
34.6 m/s
Explanation:
From conservation of momentum, the sum of initial and final momentum are equal. Momentum is a product of mass and velocity. Initial mass will be 42.8+31.5+25.9=100.2 kg
Final mass will be 31.5+25.9=57.4 kg
From formula of momentum
M1v1=m2v2
Making v2 the subject of the formula then
Substitute 100.2 kg for M1, 19.8 m/s fkr v1 and 57.4 kg for m2 then
