The force of friction on the toy is 2.10 N and it acts opposite to the direction of its motion.
A force called friction prevents one solid object from rolling or sliding over another. Although frictional forces, such the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion.
Given parameters:
mass of the toy dog: M = 0.398 kg.
Applied force: F = 4.63 N.
Angle of application of force: θ = 63.0°
Hence, horizontal component of applied force = F cosθ
= 4.63 × cos63.0° N
= 2.10 N.
As the child drags a 0.398 kg toy dog across flat ground at constant speed, this component of applied force is nullified by force of friction.
Hence, the force of friction on the toy is 2.10 N and it acts opposite to the direction of its motion.

Answer:
-2.1 N
Explanation:
A. C-2
B. C-6
C. C-8
D. C-14
Answer: Option B
Explanation:
When the thermal energy is transferred from a hotter body to the colder body then the transfer of energy takes place until the temperature of both the objects are same.
The energy from the hotter body is transferred to the colder body. Example: The heat transfer from the hotter water takes place into the colder water.
The energy transfer will stop only when the temperature of both the water will be same.
