From the information given, the lab cart has a mass of 0.5 kg and the student exerts a force of 3N on it.
We use the formula F = MV
Where F = Force, M = mass and V = velocity
In our case, F = 3N (or 3 Kg m/s²) , M= 0.5 kg , V is unknown.
F= MV → MV = F → V = F / M
V = 3 kg m/s² / 0.5 kg
V= 3 / 0.5
V = 6 m/s²
Therefore the acceleration of the cart 6 m/s²
Answer:

is copied or as the result of environmental factors. All BUT ONE of the statements below correctly
describes or explains genetic mutations.
A) Mutation can disrupt normal cell activity and cause diseases, like cancer.
B) Mutations in parents' cells are then passed down to offspring via reproduction,
C) Our cells can recognise any potentially mutation-causing damage and repair it Eliminate
before it permanent.
D) Mutations can occur as the result of exposure to environmental factors such as
smoking, toxins and radiation.
