hello everyone, i saw this two problems on a sample oxford admission test and i was wondering what the answer is ...
1)
If you run at 5 m/s towards a plane mirror, at what speed does your
image approach you?
A 5 m/s
B 2.5 m/s
C 10 m/s
D 15 m/s
i think the right answer is A... am I right?
2)
A baby's bath should be at a temperature of 37C. The bath already
contains 10 kg of water at 15C. Approximately how much hot water,
with a temperature of 50C, should be added to achieve the desired
temperature?
A 10 kg
B 15 kg
C 17 kg
