Answer:
Driver hits the dog
Explanation:
From kinematics equation
and making a the subject
F=ma=800*-4=-3200 N
The driver is required to apply a force of 3200 N to effectively not hit the dog. However, when the driver applies 2000 N, this is less the required force by 1200 N hence the driver hits the dog.
B you wold go from the crust all the way to the inner core
Answer:
C) Emf is the force exerted on a single charge to move it from one terminal to the other of an emf device.
Explanation:
Electromotive force, abbreviation E or emf, electrical energy per unit supplied from an energy source, such as an electrical generator or a battery. In the engine or battery, electricity is transformed from one source to another as the device works on the electrical charge that is passed within itself.
In physics it is defined as Work done by a cell or battery in moving a unit charge from its one terminal to the other, against the potential.
Hence C is correct
I believe the answer is sample a
