5 0

Answer:

1.5 miles

Explanation:

Given that,

Speed of dog, v = 15 mph

Time taken by the dog, t = 0.1 h

We need to find the distance travelled by the dog. We know that, distance is the product of speed and time. So,

d=vt

d=15\times 0.1\\\\d=1.5\ \text{miles}

Hence, the dog will cover a distance of 1.5 miles.

How many calories of heat are required to raise the temperature of 1.00kg of water from 10.2 degrees Celsius to 26.8 degrees Cel
Vika [28.1K]

Answer:

Explanation:

we know that specific heat is the amount of heat required to raise the  temperature of substance by one degree mathmeticaly

Q=mcΔT

ΔT=T2-T1

ΔT=26.8-10.2=16.6

C for water is 4.184

therefore

Q=1.00*4.184*16.6

Q=69.4 j

now we have to covert joule into calorie

1 calorie =4.2 j

x calorie=69.4 j/2

so 69.4 j =34.7 calorie thats why 34.7 calorie heat is required to raise the temperature of water from 10.2 to 26.8 degree celsius
